The major product of the following reaction is

(A)(see structure)
✓ Correct
(B)(see structure)
(C)(see structure)
(D)(see structure)

Answer: (A)

Solution

This is a Birch reduction, where aromatic rings are reduced by sodium in liquid ammonia with an alcohol. The reaction selectively reduces the aromatic ring to a 1,4-cyclohexadiene derivative. The methoxy group (electron-donating) directs reduction to give the unconjugated diene, and the nitro group remains unchanged. Therefore, option (A) is correct.
