The correct answer is (b), Treaty of Lahore.
The Treaty of Lahore was signed on 9 March 1846 between the British East India Company and Maharaja Dalip Singh, the last Maharaja of the Sikh Empire. The treaty marked the end of the First Anglo-Sikh War and the annexation of Punjab by the British.
The treaty was signed at Lahore, the capital of the Sikh Empire. The British were represented by Sir Henry Lawrence, while the Sikhs were represented by Raja Gulab Singh.
The treaty stipulated that the Sikh Empire would cede all of its territory to the British, except for the princely state of Jammu and Kashmir, which was given to Raja Gulab Singh. The British also agreed to pay a pension to Maharaja Dalip Singh.
The Treaty of Lahore was a major turning point in the history of India. It marked the end of the Sikh Empire and the beginning of British rule in Punjab.
