The correct answer is: a) Disarm the Manipuri army.
The Manipur Conspiracy Case of 1891 was a conspiracy by the Manipuri people to overthrow the British Raj. The conspiracy was led by Tikendrajit Singh, the Maharaja of Manipur. The British had been interfering in the internal affairs of Manipur for many years, and the Manipuri people were unhappy with this. They also felt that the British were trying to suppress their traditional culture and religion.
In 1891, the British decided to disarm the Manipuri army. This was the final straw for the Manipuri people, and they decided to rise up against the British. The conspiracy was unsuccessful, and Tikendrajit Singh was executed. However, the Manipur Conspiracy Case showed the British that the Manipuri people were not going to tolerate their interference in their affairs.
The other options are incorrect because:
- Option b) is incorrect because the British did not interfere in the royal succession. The Maharaja of Manipur was always chosen by the Manipuri people.
- Option c) is incorrect because the British did not impose heavy taxes on the Manipuri people.
- Option d) is incorrect because the British did not suppress traditional religion in Manipur.
