Here we need to see which lens or mirror forms which type of image. If a lens is unable to form a particular image then provide a suitable reason for it. Here concave lens and convex lens are opposite to each other and plane mirror doesn’t form an inverted image.

Complete step-by-step solution:-
There are many types of lenses that are available, but the most common is a concave lens. The concave lens is a lens that is having at least one surface curved inwards. It is a lens that is diverging in nature, meaning that light rays which have been refracted spreads out through the lens. The concave lens is thicker on the edges than its center. A concave lens always forms a virtual image, it cannot form a real image nor an inverted image. So, option “2” is ruled out.
A plane mirror is a mirror with a flat reflective surface. Here the angle of incidence and angle of reflection are equal. The image formed by the plane mirror is virtual and it is of the same size of the object. The plane mirror due to its physical properties cannot form an inverted image.
Convex lens is a lens that is opposite to a concave lens. In convex lenses unlike in concave lenses the light rays converge. In other words it converges the incident rays into its principal axis and also unlike the concave lens the convex lens is thicker in the middle and thinner at the edges. The edges of the convex lens are curved outwards rather than being curved inwards. When the light is particularly focused beyond the focal length of the lens then the image appears to be smaller and inverted.
Final Answer: Option “1” is correct. Only convex lenses have the ability to form inverted images.

Note:- Here we need to discuss in detail about each option and explain about its characteristics. Also provide a reasonable explanation about why a particular lens or mirror is unable to form an inverted image.
