A converging lens is that which:
- Collect rays
- Reflect rays
- Forms virtual image
- None of the above

Hint:-
- Lenses can be used to focus the light.
- The concave image is always virtual.
- Virtual images can't be obtained on the screen.

Complete step by step solution:-
a. Collect rays
 The converging lens is the rays to a single point. Example of the converging lens is a convex lens. The parallel light ray incident through a convex lens focuses to one point. In convex lenses there are virtual images and real images which depend upon the position of the object.

b. Reflect rays
The rays are reflected in mirrors. Different types of mirrors are there based on the geometry. The reflected surface is a plane called plane mirrors. If it is a spherical surface, it is called spherical mirrors.

c. Forms virtual image
Virtual image is the image we can’t obtain on screen. Converging lenses can’t always produce a virtual image. But, the diverging lens always produces a virtual image. Concave lens is an example of diverging lenses. Mostly it forms a real image which can be projected on the screen. When the object is very near to the convex lens there is a virtual image obtained.

d. None of the above

So the answer is (A) Collect rays

Note:- Converging lenses are used in microscopes telescope et, because of their property of converging the light from far to one point. So we can obtain the image from far objects in the telescope and bigger images in the microscope. Basically the refraction of light is used in lenses. And reflection is used in the mirror.
