The correct answer is option 2, protecting the sovereignty of the Khalifa.

The Khilafat Movement was a political movement in India during the early 20th century. It was initiated by Muslims with the aim of protecting the sovereignty and rights of the Khalifa, who was the political and religious leader of the Muslim community worldwide, especially in the Ottoman Empire. The movement emerged in response to the British decision to end the caliphate and dismantle the Ottoman Empire after World War I.

The movement gained significant support among Indian Muslims, who viewed the caliphate as a symbol of Muslim unity and power. They believed that the dethroning of the Khalifa would lead to the loss of Muslim rights and would undermine their religious and cultural identity. Therefore, they organized protests, boycotts, and demonstrations to express their opposition to the British government`s actions.

It is important to note that while the Khilafat Movement was primarily focused on protecting the Khalifa`s sovereignty, it also had some overlapping goals with the Indian national movement, such as opposition to British rule. However, the primary objective of the movement was to safeguard the Khalifa`s position, making option 2 the correct answer.
