A concave lens always forms an image which is
(A) Real, inverted, and diminished
(B) Real, erect, and diminished
(C) Virtual, erect, and magnified
(D) Virtual, erect, and diminished

Hint: the images that are formed from the convex and concave lens, depend upon the structure of the lens. The concave, consists of certain properties. Knowing the properties, will help in finding the characteristics of the object formation.

Complete step by step answer
The concave lens always forms a virtual, erect and diminished image. As we can observe in the ray diagram which is provided below.



Therefore, we can say that the correct answer to the question which is mentioned in option D.

The property of concave lenses that we should be knowing is that it is thinner in the middle. Which means that if there are some 55parallel rays of light passing through any concave lens then the refracted rays will divert so that they appear to come from one single point which is known as the principal focus.

Additional information:
Concave lens is also known as a diverging lens. This is because it possesses one surface which is curved inward. Concave lens spreads out light rays that are then refracted through it.
A concave lens is used to correct short sightedness which is also known as myopia.

Note: A concave mirror or a converging lens will only produce a real image if the image is located beyond the focal point. By the focal point we mean more than one focal length away. The image that will be formed will be upright and reduced in size.
