Answer
The correct answer is:
(d) $~v_A \lt v_B~~$ and $~~a_A = a_B$
Work Step by Step
The correct answer is:
(d) $~v_A \lt v_B~~$ and $~~a_A = a_B$
The horizontal component of velocity is constant. At the highest point, the vertical component of velocity is zero. Therefore, the speed is a minimum at the highest point.
During the motion, the only force is the gravitational force, so the acceleration is $g$ during the whole motion.
