Answer 2

Answer: The answer is -- c) the boy can't see his feet

Explanation:

In the picture the height of the boy is from point A to point B.

If the boy stands at the front of the mirror then he can only see the upper vision range and the lower vision range. For the upper vision range the boy can see his hair and for the lower range the boy can only see the upper leg but not his feet.
