In projectile motion, the angle between the instantaneous velocity and acceleration at the highest point is$ 90{}^\circ $. Reason: At the highest point, velocity of projectile will be in horizontal direction only.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
