Correct answer is (a) Stable equilibrium
Easy explanation: The body is said to be in the state of stable equilibrium if it returns to its original equilibrium after giving it a slight displacement. In unstable equilibrium, the body does not return to its original equilibrium and moreover also does not achieve any other equilibrium. In neutral equilibrium, the body attains a new equilibrium every time it is displaced.
