C. vx

F. ax

G. ay

Explanation:

The projectile moves along a curved path towards the ground, so its x and y positions change.

Since there is no applied force in the x-direction, the acceleration in the x-direction is zero. This means, ax and vx do not change.

The projectile is under the influence of gratify, which is directed towards the ground. So its velocity increases, because its y-component of the velocity increases.

However, the y-component of its acceleration is constant, since it is gravitational acceleration.
