Answer:
B. They cannot make light rays converge.
Step-by-step explanation:
Real images are defined as the image in which light rays will converge at a point after reflection through the mirror
if the light rays converge and meet at a point in front of mirror then the point of convergence is known as real image
while if the light rays will not converge and the light will diverge after reflection through the mirror then it will appear to meet at a point behind the mirror
this imaginary point is known virtual image
so here in case of plane mirror and convex mirror the light rays will not converge at a point after reflection through the mirror
so it can not form real images
so correct answer will be
B. They cannot make light rays converge.
