F. passes through the boundary

Step-by-step explanation:

(This Answer is correct on Edge 2021)

A. "changes direction" is INCORRECT bc while the incident ray does change direction in refraction, it also changes direction in reflection, and we require only the characteristics that are present in refraction and not reflection.

Answer 2

changes speed

bounces off the boundary
