Correct option is (a) True

Explanation: Consider the problem of (linear) bending of beams according to the Euler-Bernoulli beam theory. The principle of minimum total potential energy states that if the beam is in equilibrium, then the total potential energy associated with the equilibrium conﬁguration is the minimum; i.e., the equilibrium displacements make the total potential energy a minimum. Thus, solving the equations governing the equilibrium of the Euler-Bernoulli beam is equivalent to minimizing the total potential energy.
