The correct answer is Mohammad Iqbal .

The proposal for a separate Muslim state in India was first put forward by Mohammad Iqbal, also known as Allama Iqbal, who was a poet, philosopher, and politician. He is considered to be one of the most important figures in the movement for the creation of Pakistan, which eventually led to the partition of India in 1947.

Iqbal first proposed the idea of a separate Muslim state in a speech he delivered at the All India Muslim League conference in Allahabad in 1930. In this speech, he argued that Muslims in India were a separate nation and that they needed a separate state to protect their rights and interests.

Iqbal’s idea was later adopted by Muhammad Ali Jinnah, who became the leader of the Muslim League and the main advocate for the creation of Pakistan. Jinnah saw the creation of a separate Muslim state as the only way to safeguard the interests of Muslims in India, who he felt were marginalized and oppressed by the Hindu majority.

The demand for a separate Muslim state gained momentum in the years leading up to India’s independence from British rule in 1947. The British government eventually agreed to the creation of two separate states – India and Pakistan – with Pakistan comprising two regions on either side of India – East Pakistan (present-day Bangladesh) and West Pakistan (present-day Pakistan).

In conclusion, the correct answer to the question is option 4, Mohammad Iqbal, who first proposed the idea of a separate Muslim state in India. It is important to note that this topic is of great significance in Indian history and is often asked in competitive exams. Therefore, it is essential for students to have a clear understanding of the background and context surrounding the creation of Pakistan.
