Your small pocket camera has a telephoto setting in which the converging lens sticks far out in front of the camera body. The lens still projects a real image on film near the back of the camera body but now the lens is much farther from the film. When you shift the camera into this telephoto setting, the lens itself
A) effectively becomes more highly curved so that it bends light more strongly.
B) keeps its same curvature but its effective diameter becomes smaller.
C) effectively becomes less highly curved so that it bends light less strongly.
D) keeps its same curvature but its effective diameter becomes larger.

When the lens is moved farther from the film to achieve a telephoto setting, it effectively becomes less highly curved in terms of its optical effect. This means it bends light less strongly, allowing it to focus distant objects onto the film without requiring a physically larger lens. This adjustment changes the focal length to capture distant scenes without altering the physical curvature of the lens itself.
