Answer:
(a) Concave lens.
Explanation:
Images formed in a concave lens are always virtual. A virtual image is formed when the actual rays doe's not meet after refracting through the lens, instead, they appear to converge at a particular point. Such virtual images cannot be obtained on a screen as the rays are not actually meeting together.
