Solution

The correct option is D $F_{1} = F_{2}$
According to third law of motion: For every action, there is an equal and opposite reaction. So, when you push a spring with a force $F_{1}$ , the spring also pushes up on your hand with a force $F_{2}$ of having same magnitude but in opposite direction hence, $F_{1} = F_{2}$
