Which one of the following is not a correct statement ?

Option A presents a fact. Dr Manmohan Singh served as the Finance Minister in the Union Government from 1991 to 1996. Option B also presents a fact. Dr Manmohan Singh served as the Governor of the Reserve Bank of India from 1982 to 1985. He also became the UGC chairman in 1991. Therefore, option C is also true. Dr. Manmohan Singh became Prime Minister as a member of the Rajya Sabha (the upper house), not the Lok Sabha (the lower house). He was elected to the Lok Sabha in 1999 but lost that election, while he was elected to the Rajya Sabha multiple times and served there when he became Prime Minister in 2004. Option D is the only false statement, and it is the correct answer.
