Correct Answer: Punjab

Solution : The correct answer is Punjab .

In 1848, Dalhousie unveiled a plan dubbed the "Doctrine of Lapse". If a king did not have a natural successor, the British would take control of the kingdom under this policy. It prohibits the adoption of sons. The Doctrine of Lapse was not strictly applied in the annexation of Punjab. Instead, a treaty was negotiated, and the region was annexed to the British East India Company after the Second Anglo-Sikh War in 1849.
