The correct option is C Lord Ellenborough
After being defeated by the Afghans, the Governor-General of India, Lord Ellenborough decided to make the Indus river a frontier for free navigation to fight the Afghans and the Sikhs. For this strategy to work, Sindh seemed like a perfect region to start, and he planned to annex Sindh. The Amirs of Sindh were defeated. The British, led by Charles Napier, annexed Sindh in March, 1843. This raised alarm bells for the Sikhs that the British wanted to annex Punjab, and the Sikhs started preparing for war.
