A student studies that a convex lens always forms a virtual image irrespective of its position. What causes the convex mirror to always form a virtual image?

Q. A student studies that a convex lens always forms a virtual image irrespective of its position. What causes the convex mirror to always form a virtual image?

A.            because the reflected ray never intersects

B.            because the reflected ray converges at a single point

C.            because the incident ray traces its path back along the principal axis

D.            because the incident ray of a convex mirror gets absorbed in the mirror
