Explanation
The currency note of Re 1/- (Rupee One) is printed by the "Government of India".
While the Reserve Bank of India (RBI) is responsible for the design, production, and overall management of currency notes, the actual printing of Re 1/- notes is done by the Government of India's Security Printing and Minting Corporation of India Limited (SPMCIL).
Thus, the correct answer is A: Central Government.
