A particle moving about its equilibrium position with equation $y=-a x-b t$. Interpret the condition

• A

  It will always perform the SHM.
• Correct answer
  B

  It can never perform the SHM.
• C

  It can perform SHM only when $t \geq \frac{b x}{a}$.
• D

  It can perform SHM only when $t \leq \frac{b x}{a}$.

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