(D) For $A$ (Concave Mirror): It can form a real image (when object is beyond $F$), a virtual image (when object is between $P$ and $F$), a magnified image (when object is between $P$ and $2F$), and an image at infinity (when object is at $F$). Thus, $A \rightarrow p, q, r, s$.For $B$ (Convex Mirror): It always forms a virtual image. The image is diminished, so it cannot be magnified. It can form an image at infinity if the object is at $F$. Thus, $B \rightarrow q, s$.For $C$ (Convex Lens): It can form a real image (when object is beyond $F$), a virtual image (when object is between $O$ and $F$), a magnified image (when object is between $O$ and $2F$), and an image at infinity (when object is at $F$). Thus, $C \rightarrow p, q, r, s$.For $D$ (Concave Lens): It always forms a virtual image. The image is always diminished, so it cannot be magnified. It can form an image at infinity if the object is at $F$. Thus, $D \rightarrow q, s$.
