Answer:

The action force is the force that causes a reaction, in this case, it will be flicking the switch, the resistance of the switch of being moved is what you "fell" as the resistance force. The correct option is A

Again, an action force is a given force in one direction, in this case, the spring is not stretching, but there is a force applied on it, so the action force will be the force of pulling the spring from both ends, in this case, the correct option is C
