Solution

The correct option is D When it is at a displacement $\pm \frac{A}{\sqrt{2}}$ from the equilibrium point and moving away from the equilibrium point.
Maximum restoring force will be observed when the displacement of simple harmonic motion oscillator is at a length of $\pm \frac{A}{\sqrt{2}}$ away or towards the equilibrium point.
