Option D — Currency, Communication, Defence
These are subjects of national importance listed under the Union List, on which only the Union Government can make laws.
The source passage clearly states that the Union List includes defence, foreign affairs, banking, communications, and currency. Option D matches three of these exactly. Options A, B, and C mix State List subjects (police, agriculture, trade, irrigation) and Concurrent List subjects (education, marriage) with Union List subjects, making them incorrect.
