v – t graph of a graph of a particle in SHM is as shown in figure. Choose the correct

At A particle has zero velocity and approaching positive x-axis. It is at its extreme  position with maximum displacement and maximum acceleration directed towards  negative x-axis.At B particle has positive velocity and approaches positive x-axis. It is at its mean  position with zero displacement with respect to mean position and zero  acceleration.At C particle has zero velocity and approaching negative x-axis. It is at its extreme  position with maximum displacement and maximum acceleration directed towards  positive x-axis.
