The pictures are not attached, therefore, I cannot give a specific choice.
However, I will try to help you out.
The angle of incidence is defined as the angle formed between the ray of light and the normal to the surface that the ray is falling on.
The angle of incidence can be shown in the attached image.
Therefore, for your question, choose the image on which the above description applies.
Hope this helps :)

Answer:
0.57 m
Explanation:
First of all, we need to calculate the time it takes for the ball to cover the horizontal distance between the starting position and the crossbar. This can be done by analzying the horizontal motion only. In fact, the horizontal velocity is constant and it is
And the distance to cover is
d = 19 m
So the time taken is
Now we want to find how high the ball is at that time. The initial vertical velocity is
So the vertical position of the ball at time t is
where g = 9.8 m/s^2 is the acceleration of gravity. Substituting t = 2.04 s, we find
The crossbar height is 3.05 m, so the difference is
So the ball passes 0.57 m above the crossbar.
