Spring controlled governor can be made stable by decreasing the spring stiffness. .
For a stable governor, if the equilibrium speed increases, the radius of governor balls must also increase.
A governor is said to be unstable if the radius of rotation decreases as the speed increases.
For a stable governor, if the equilibrium speed increases, the radius of governor balls must also increase.

B is right because the spring controlled governor is found unstable. It can be made stable by.
Decreasing the spring stiffness. Because for stable required spring always compression so stiffness is less so spring is more in compression.

Answer become A Because, sensitively is reciprocal of stability. And stiffness is reciprocal of sensitivity.
