<h3>What is Simple harmonic motion?</h3>

Simple harmonic motion is periodic motion caused by a restoring force that is proportionate to the deviation from equilibrium.

Simple harmonic motion is periodic motion but many other conditions are dependent.

The time period of the pendulum is found as;

\rm T= 2 \pi \sqrt{\frac{L}{g} } \\\\ \rm 1.87 \ sec= 2 \times 3.14  \sqrt{\frac{L}{9.81 m/s^2} } \\\\ L=0.087 \ m

The length of the pendulum is 0.087 m

Hence, option d is correct.
