To determine the force, we use the Hooke's Law which says that the force required to extend or compress a certain spring is proportional directly to the total change in distance. It is expressed as:
F = kx where k is the spring constant and x is the distance
We calculate as follows:
F = 25 (0.25)
F = 6.25 N
Therefore, the correct answer is option 3, 6.3 N.
