A concave mirror cannot be used as:(a) a magnifying mirror (b) a torch reflector (c) a dentist's mirror (d) a real view mirror

(d) a rear view mirror

Explanation

A concave mirror cannot be used as a rear view mirror because it forms an inverted image of distant objects, due to which all the vehicles will be seen running upside down in the mirror.

In a concave mirror, when an object is at distant or at infinity then the image forms at the focus. The nature of the image is real & inverted, and its size is highly diminished.
