The correct answer is C. Keyhole and saddle. In the context of spectacle frames, the bridge refers to the part of the frame that rests on the nose. Keyhole bridges have a unique shape resembling a keyhole, while saddle bridges have a curved shape that sits comfortably on the nose.

Options A, B, and D do not refer to different types of bridges found on spectacle frames. Nose and cheek refer to the areas of the face where the frame rests rather than types of bridges. Rimless and full-rim describe different styles of frame construction. Aviator and cat-eye are styles of frame shapes, not bridge types.
