Question

As it speeds up the drag force gets bigger.

As it speeds up the net force on the soccer ball gets smaller.

As it speeds up the magnitude of the acceleration gets less

As it speeds up the acceleration will eventually reach zero - assuming it falls from a great enough height.

As it speeds up the drag force gets bigger.

As it speeds up the net force on the soccer ball gets smaller.

As it speeds up the magnitude of the acceleration gets less

As it speeds up the acceleration will eventually reach zero - assuming it falls from a great enough height.

the drag force is proportional to the square of the velocity. so more velocity means more drag.

As the ball falls through a great height, net force on the ball is zero. Thus aacceleration=0

so options (a) and (d) are correct.
