Option A — Concurrent List – Education
Education is placed in the Concurrent List under the 42nd Constitutional Amendment, 1976, meaning both Centre and State can legislate on it.
Defence belongs to the Union List; Police belongs to the State List; Trade (domestic) generally falls under the State List. Education was moved to the Concurrent List by the 42nd Amendment, making Option A the only correct match.
