Answer

(b) real, virtual

Reason — A concave mirror has a real focus because the light rays incident parallel to the principal axis, after reflection actually pass through the focus.
A convex mirror has a virtual focus because the light rays incident parallel to the principal axis, appear to come from the focus after reflection from the mirror.
