\nThe Post Office (Amendment) Bill, 1986, was passed by Parliament during the tenure of Prime Minister Rajiv Gandhi. The President at that time was Giani Zail Singh. President Giani Zail Singh famously did not give his assent to the bill nor did he return it for reconsideration. Instead, he kept it pending, effectively using a pocket veto. The bill eventually lapsed.
\nThe question asks which President “sent back” the bill for reconsideration. Giani Zail Singh did not send it back.
\nAmong the Presidents listed, K. R. Narayanan (President from 1997 to 2002) is well-known for actively exercising the power to return bills for reconsideration under Article 111 of the Constitution. Notably, he sent back the recommendations of the Union Cabinet regarding the imposition of President’s Rule under Article 356 for Uttar Pradesh (1997) and Bihar (1998), and also returned the Constitution (Eighty-fourth Amendment) Bill, 2000 (regarding delimitation).
\nWhile K. R. Narayanan did not interact with the 1986 Post Office Bill (as it lapsed before his presidency), the question asks *who* among the options “sent back” bills for reconsideration, linking it to the context of a significant controversial bill. Given that Giani Zail Singh did *not* send the 1986 bill back, and K. R. Narayanan is the prominent President among the options known for using the “send back” power, option D is the most likely intended answer, despite the potential inaccuracy in associating K. R. Narayanan directly with the 1986 bill. The question likely tests the knowledge of which President significantly used the power to return bills.
