The British East India Company annexed the Ambala principality due to the reason of ………. .

The correct answer is: A. death of Sardarni Indra Kaur

Sardarni Indra Kaur was the last ruler of the Ambala principality. She died in 1839, and the British East India Company annexed the principality shortly thereafter.

The other options are incorrect because:

• Nawab Jabit Khan was a Mughal nobleman who served as the governor of Ambala from 1783 to 1793. He did not revolt against the British East India Company.
• Mai Sukhan was a Sikh woman who was the wife of Maharaja Ranjit Singh. She died in 1838, one year before the British East India Company annexed the Ambala principality.
