Correct Answer: Option A
Explanation

The direction of the force is determined by Fleming's left-hand rule:

Field (Forefinger): N to S (right to left).

Current (Middle finger): P to Q (downwards).

Force (Thumb): When aligning fingers as described, the thumb points upwards.

This force acts on the segment PQ, causing the initial upward movement.
