Answer 1

Explanation

Shutter- A device that allows light into a camera's lens aperture, allowing the film to be exposed.

1. The shutter is one of two techniques to restrict the amount of light entering the camera, together with the aperture.
2. The shutter controls the amount of light that reaches the light-sensitive surface.
3. The shutter opens, allowing light into the camera and exposing the film or sensor to light, before closing.

Hence, the correct answer is option (A) shutter.
