Detailed explanation-1: -The correct option is C convex lens .

Detailed explanation-2: -A magnifying glass is a convex lens used to make an object appear much larger than it actually is. This works when the object is placed at a distance less than the focal length from the lens. The image is: upright (the right way up)

Detailed explanation-3: -Convex lenses are used in eyeglasses for correcting farsightedness, where the distance between the eye’s lens and retina is too short, as a result of which the focal point lies behind the retina. Eyeglasses with convex lenses increase refraction, and accordingly reduce the focal length.

Detailed explanation-4: -The distinguishing feature of the magnifying glass is its structure-a bi-convex lens (one that is convex on both sides) situated in a frame and attached to a handle. The lens may be constructed of glass or plastic, and the handle of materials such as wood, plastic, and metal.

Detailed explanation-5: -A magnifying glass uses a convex lens because these lenses cause light rays to converge, or come together.
