In an oscillating system, damping results in dissipation of the stored energy. The following figure shows the variation of displacement x with time t for an oscillating system. Which of the following statements best describes this physical phenomenon.

A

Oscillatory motion of an object without damping

B

Oscillatory motion of an object with damping such that time measurement was started when the system was at the mean position

C

Oscillatory motion of an object with damping with decreasing time period

D

Oscillatory motion of an object with damping such that time measurement was started when the system had maximum potential energy
