Solution

The correct options are
A When force is applied at $A$ , the rod will move in clockwise.
D When force is applied at $B$ , the rod will move in counterclockwise.
Case 1: When vertically upward force is applied at $A$ .
The rod will move in the clockwise direction.

Case 2: When vertically upward force is applied at $B$ .
The rod will move in the counterclockwise.
