At the point of a projectile motion, acceleration and velocity are perpendicular to each other?

View answer and explanation

Correct option: C

At the top most point

Option C (At the top most point) is correct because at the highest point of the trajectory, the vertical component of velocity is zero, and the acceleration due to gravity is perpendicular to the horizontal velocity.
