The correct choice is (a) only one switch is operated

The explanation is: For IVth quadrant, only CH4 is operated.

The difference between “operated” and “on” should be noted. Operated means it can is literally operated i.e. it is switched on and off and on and off, whereas on means it is on continuously.
