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.
