Concept:A larger pinhole allows more light rays from the same point of the object to enter, causing overlapping images on the screen.Explanation:In a pin-hole camera, a small pinhole produces a sharp image because only a narrow beam of light from each object point reaches the screen.When the pinhole is enlarged, multiple rays from the same object point strike different positions on the screen.This overlapping of rays makes the image appear blurred.Answer:A. blurred.
