According to Lenz's Law, the direction of the induced current is such that it opposes the change in magnetic flux that produced it.

1. Solenoid-1 (Magnet Moving Away): As the magnet moves away from Solenoid-1, the magnetic flux through it decreases. The induced current will flow in a direction to create a magnetic pole that attracts the retreating magnet (e.g., if the South pole is trailing, a North pole is induced at the end facing the magnet). This requires the current to flow in a specific direction (e.g., $A \to B$) to maintain the flux.

2. Solenoid-2 (Magnet Moving Towards): As the magnet approaches Solenoid-2, the magnetic flux through it increases. The induced current will flow in a direction to create a magnetic pole that repels the approaching magnet (e.g., if the North pole is leading, a North pole is induced at the end facing the magnet). This requires the current to flow in the opposite sense relative to the motion (e.g., $D \to C$).

(Note: The exact direction $A \to B$ vs $B \to A$ depends on the specific winding direction and magnet polarity shown in the missing diagram, but based on the probable answer, the currents oppose the motion at both ends.)
