A particle is performing SHM starting from extreme position. Graphical representation shows that, between displacement and acceleration, there is a phase difference of

• A

  $0\mathrm{ rad}$
• B

  $\frac{\pi }{4} \mathrm{r}\mathrm{a}\mathrm{d}$
• C

  $\frac{\pi }{2} \mathrm{r}\mathrm{a}\mathrm{d}$
• Correct answer
  D

  $\pi \mathrm{r}\mathrm{a}\mathrm{d}$

Hence, the correct answer is option: 'D'.
