b. The mirror height should be equal to your full body height; distance does not matter.
c. The mirror height should be greater than your eye level; distance matters.
d. The mirror height should be greater than your full body height; distance matters.

Answer 1

The mirror should be taller than your full body height and its size does not depend on your distance from the mirror.

Step-by-step explanation:

The mirror height should be greater than your full body height and its top edge should be at the level of your eyes. This way, you will be able to see your entire body from head to toe in the mirror.

The size of the mirror does not depend on your distance away from the mirror. Whether you are close to the mirror or far away, the mirror should still be taller than your full body height in order for you to see your entire reflection.

Here is a sketch to help illustrate:
