Explanation / Answer

Part 1

Option 2, when the lower half of the mirror is covered.

Part 2

When the lower half of the mirror is covered, the reflected light rays from the arrow will not enter her eyes. Thus, no image will be seen. The angle of incidence is equal to the angle of reflection. For this condition to satisfy, the lower half of the mirror must not be covered.

She will see the image even if the upper half of the mirror is covered.
