Since the mirror is a plane mirror the light rays will travel parallel to each other and come back the same way. There will be no divergence or convergence of the rays and hence the image will be at the same distance, that is 15 millimetres or (c). The height of the object will not make any difference

The distance of the object from the plane mirror=The distance of the image from the plane mirror(always).
So,answer is C)15 mm.

The image appears to be 15 mm behind the mirror

You should know that in case of plane mirror the object distance is always equal to image distance . So no doubt , the answer is 15.0 mm.

It's a reflection, so the light has to travel from the object to the mirror and back.

c because since its a plane mirror it would reflect the object in it at the same distance it is in reality

it's 15 mm the height doesn't matter. It's viewed with the same distance.
