$(a)$. An image that cannot be obtained on a screen is called $\underline{Virtual\ image}$.

Explanation:

There are two types of images formed by mirrors and lenses-

1. Real image- An image that can be obtained on a screen is called a real image.

2. Virtual images- An image that can't be obtained on the screen is called a virtual image.

$(b)$. Image formed by a convex $\underline{mirror}$ is always virtual and smaller in size.

Explanation:

Convex mirrors always form virtual and smaller in size images of an object.

$(c)$. An image formed by a $\underline{plane}$ mirror is always of the same size as that of the object.

Explanation:

An image formed by a plane mirror is always virtual, erect, upright, and of the same size as the object.

$(d)$. An image which can be obtained on a screen is called a $\underline{real}$ image.

Explanation:

Real images formed by mirrors or lenses can be obtained on the screen While virtual images can't be obtained on the screen.

$(e)$. An image formed by a concave $\underline{lens}$ cannot be obtained on a screen.

Explanation:

The image formed by a concave lens is always virtual, erect, and smaller in size than the object. It is diverging in nature. Therefore, virtual images formed by a concave lens can not be obtained on the screen.
