The strong Kisan Sabha movement in Gaya District of Bihar during 1931 was led by Yadunandan Sharma. He was a prominent leader of the All India Kisan Sabha, which was founded in 1936 and became one of the largest peasant organizations in India. The Kisan Sabha movement was a peasant movement that aimed to improve the economic conditions of farmers and agricultural workers, who were often exploited by landlords and moneylenders. The Gaya District movement was particularly significant because it was one of the earliest and most successful Kisan Sabha movements in India. Yadunandan Sharma was a key figure in this movement and played an important role in organizing the peasants and workers of Gaya District to demand better wages, working conditions, and land rights. His leadership was instrumental in the success of the Kisan Sabha movement in Gaya District and helped to inspire similar movements throughout the country.

Harshacharita, a biography of King Harsha, written by Banabhatta, indicates that Brihadratha, the last Mauryan emperor, was assassinated by Pushyamitra, the founder of the Shunga dynasty, in 185 BCE. The Puranas also mention this event, but they give a different account of the assassination. The Gargi Samhita does not mention this event. However, the Harshacharita is considered a reliable source as it was written during the Gupta period, which was after the events it describes, and Banabhatta was a courtier of King Harsha.

Chandragupta I, who ruled from around 320 to 335 CE, was the first Gupta ruler to assume the title of Maharajadhiraja, which means “king of kings”. This title was a significant departure from the earlier Gupta rulers, who had used the title of Maharaja or “great king”. The adoption of the title of Maharajadhiraja was a reflection of the expanding political and military power of the Gupta Empire under Chandragupta I. His reign is also significant because he was the first Gupta ruler to establish matrimonial alliances with other royal families, which helped to strengthen the Gupta Empire.

Taila II of the Western Chalukya dynasty overthrew the Rashtrakutas in 973 AD. The Rashtrakuta dynasty ruled parts of present-day Karnataka, Maharashtra, and Gujarat from the 8th to the 10th century. They were known for their patronage of art, architecture, and literature, including the famous rock-cut cave temples of Ellora. However, by the mid-10th century, their power began to decline, and they were eventually conquered by the emerging Chalukya dynasty. Taila II, the founder of the Western Chalukya dynasty, is credited with consolidating power and defeating the Rashtrakutas, marking the beginning of a new era in South Indian history.

The correct answer to the question is option 1) It is the highest altitude tunnel in the world.

The Atal Tunnel, also known as the Rohtang Tunnel, is a tunnel in India that connects Manali to Lahaul-Spiti valley in the state of Himachal Pradesh. It is named after the former Indian Prime Minister Atal Bihari Vajpayee.

The following statements are correct about the Atal Tunnel:

1. It was inaugurated on 03 October 2020 in Rohtang: The Atal Tunnel was inaugurated by the Indian Prime Minister Narendra Modi on 3rd October 2020 at Rohtang.

2. It connects Manali to Lahaul-Spiti valley: The Atal Tunnel is a 9.02 km long horseshoe-shaped tunnel that connects Manali to Lahaul-Spiti valley. It is located at an altitude of 10,040 feet above sea level.

3. It is capable of handling 5000 cars and 2500 trucks per day with maximum speed of 80 kmph: The Atal Tunnel is a 10.5-metre-wide, two-lane tunnel that is capable of handling a maximum traffic of 3,000 cars and 1,500 trucks per day. It has a maximum speed limit of 80 kmph.

Therefore, option 1) is incorrect because the Atal Tunnel is not the highest altitude tunnel in the world. However, it is one of the longest tunnels in the world at such high altitude.
