Answer:
The answer is 3.
Explanation:
All three students can see the images of the other two.
- At the first point A, two rays will travel to both student B and C.
- In the same way, rays emanating from student B will travel to both A nd C.
- Similarly, rays from point C will travel to both A and B.
This is possible because B is the midpoint of the mirror and A and C are both equidistant from B.
Hence the answer is three.
