The correct option is C. toward the floor.
The magnetic force on the moving negative charge acts towards the floor.
<u>Explanation</u>:
The direction of the force applied on the moving charged particle placed in the magnetic field can be determined with the help of Fleming’s Left hand rule.
The current flows in the direction opposite to the direction of electron. If the electron moves from negative terminal to positive terminal, then the current will flow from positive terminal to negative terminal.
As given, the direction of electron- South to North
So the direction of current will be- North to South
Using Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.
