When was Awadh annexed by Lord Dalhousie?

The correct answer is Option 4 - 1856

Awadh was annexed by Lord Dalhousie, the Governor-General of India, in 1856. This annexation was carried out under the Doctrine of Lapse, a controversial policy through which the British East India Company annexed princely states whose rulers died without a natural heir or adopted heir. The annexation of Awadh led to widespread discontent among the people of the region and contributed to the outbreak of the Indian Rebellion of 1857.
