A sphere of mass m1, which is attached to a spring, is displaced downward from its equilibrium position as shown above left and released from rest. A sphere of mass m2, which is suspended from a string of length / is displaced to the right as shown above right and released from rest so that it swings as a simple pendulum with small amplitude. Assume that both spheres undergo simple harmonic motion

Which of the following statements is true for both spheres?
A: The maximum kinetic energy is attained as the sphere passes through its equilibrium position.
B: The maximum kinetic energy is attained as the sphere reaches its point of release.
C: The minimum gravitational potential energy is attained as the sphere passes through its equilibrium position.
D: The maximum gravitational potential energy is attained when the sphere reaches its point of release.
E: The maximum total energy is attained only as the sphere passes through its equilibrium position
