Correct answer: The given velocity-position graph depicts that the motion of the particle is SHM.
The question seems to suggest that the velocity-position graph and the functions in (A) and (C) represent SHM. Since SHM is characterized by a sinusoidal relationship between displacement and time, and velocity is proportional to the negative of displacement, the statement in (A) aligns with SHM. Thus, option (a) is correct.
