A particle of mass m is released from restand follows a

A particle of mass m is released from restand follows a parabolic path as shown. Assuming that the displacement of the mass from the origin is small, which graph correctlydepicts the position of the particle as a function of time

The given velocity-position graph depicts that the motion of the particle is SHM.
In SHM, at t = 0, v = 0 and x = x_max
So, option (a) is correct.
