(a) The mirror and lens are both convex
(b) The mirror and lens are both concave
(c) The mirror is concave but the lens is convex
(d) The mirror is convex but the lens is concave
Solution
The mirror is convex but the lens is concave
Because both convex mirror and concave lens have positive magnification.
