Bihar Politician Late Raghuvansh Prasad Singh was for the first time elected to which Lok Sabha?

The correct answer is: C. Twelfth Lok Sabha

Raghuvansh Prasad Singh was a politician from Bihar, India. He was a member of the Janata Dal (United) party and served as a minister in the government of Bihar. He was also a member of the Lok Sabha, the lower house of the Indian Parliament.

He was first elected to the Lok Sabha in the 12th Lok Sabha elections in 1998. He was re-elected to the Lok Sabha in the 13th, 14th, 15th, and 16th Lok Sabha elections. He was a member of the Lok Sabha until his death in 2020.
