The correct match is given below:

$(a)$. A plane mirror $\rightarrow$ $(v)$ The image is erect and of the same size as the object.

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

$(b)$. A convex mirror$\rightarrow$  $(ii)$. Can form images of objects spread over a large area.

Explanation:
A convex mirror has the ability to form an image of an object spread over a large area if the object is placed at a larger distance. A convex mirror always forms a virtual, upright, and diminished image of the objects

$(c)$. A convex lens$\rightarrow$ $(i)$. Used as a magnifying glass.

Explanation:
A convex lens is used as a magnifying glass in many cases as the image formed by a convex lens is always magnified and larger than the object. A convex lens is used in microscopes.

$(d)$. A concave mirror$\rightarrow$ $(iii)$. Used by dentists to see an enlarged image of teeth.

Explanation:
A concave mirror is a spherical mirror in which the reflecting surface is curved inwards. Dentists use a concave mirror to see the enlarged image of teeth since the concave mirror can form a larger image than the object. A real, enlarged, and inverted image of the object can be obtained by a concave mirror if the object is placed between the center of the curvature and the focus of the mirror.

$(e)$. A concave lens$\rightarrow$ $(vi)$. The image is erect and smaller in size than the object.

Explanation:
The image formed by a concave lens is always virtual, erect, and smaller in size than the object. It is diverging in nature.
