Explanation:

Bird wings have an airfoil shape, which is curved on the top (upper surface) and flat or slightly curved on the bottom (lower surface). This shape helps in generating lift during flight as air flows faster over the curved top, creating lower pressure above and higher pressure below the wing.

Answer:

A. Curved on top and flat or slightly curved on the bottom
