Solution:

Emf, observations indicate that if circuit is open, then opposite charges accumulate on opposite ends of conductor.

When conductor moves downward (in figure) positive charge accumulates at and negative charge at . So, emf across is induced. Flow of charge (current) is induced in closed circuit only. Emf is induced in both open and closed circuits.
Here, in this question emf is most appropriate.
