A)

Explanation:

Once released, the projectile is subject only to the influence of gravity, which is always downward, and produces on the object an acceleration of 9.8 m/s².

The vertical acceleration of the rocket only supplies an initial velocity to the projectile, in the vertical direction, upwards.
