Correct option is D
In addition to Awadh, the British annexed several territories during the 19th century under various pretexts like Doctrine of Lapse, military conquest, and political maneuvering.
Jhansi: The kingdom of Jhansi, ruled by Rani Lakshmibai, was annexed after the death of the Maharaja in 1853. The British rejected the adopted heir, leading to the rebellion in 1857.
Satara: The kingdom of Satara was annexed in 1848 by the British under the Doctrine of Lapse after the death of its ruler without a natural heir.
The annexation of Awadh, Jhansi, and Satara led to widespread discontent and played a role in the 1857 Rebellion.
The annexation of Awadh in 1856 was especially significant as it was a wealthy and strategically important region.
