The correct answer is: d) Henry Lawrence.
Henry Lawrence was a British soldier and administrator who played a crucial role in the British conquest of the Punjab. He was appointed Commissioner of the Punjab in 1846, and he quickly set about disarming potential rebels and securing the region. He also established a system of education and justice, and he helped to promote economic development. Lawrence was killed in the Battle of Chillianwala in 1849, but his legacy continued to shape the development of the Punjab for many years to come.
John Nicholson was a British soldier who also played a role in the British conquest of the Punjab. He was a brilliant military strategist, and he was instrumental in the British victory at the Battle of Gujrat in 1849. However, Nicholson was killed in the battle, and he did not have the same lasting impact on the Punjab as Lawrence did.
Lord Dalhousie was the Governor-General of India from 1848 to 1856. He was a strong advocate of British expansion, and he was responsible for the annexation of several Indian states, including the Punjab. However, Dalhousie did not play a direct role in the administration of the Punjab, and he did not have the same impact on the region as Lawrence did.
Lord Canning was the Governor-General of India from 1856 to 1862. He was responsible for dealing with the aftermath of the Indian Rebellion of 1857. However, he did not have any direct involvement in the administration of the Punjab, and he did not have the same impact on the region as Lawrence did.
