Option 3 : Statements (1), (2). (4)

A concave mirror is used in Headlights, Shaving mirrors and in Torches
A convex mirror is used as rearview mirrors.

Concave Mirror	Explanation
As a Shaving mirror	Concave mirrors at less distance produced magnified, upright images, therefore, are used as a shaving mirror
In Headlights	In case of headlights and searchlights, the light should not scatter and instead should be a parallel beam so that it can cover a longer distance. For this purpose, concave mirrors are used because a parallel beam of light is produced when the light source is placed at the focus of a concave mirror.
In Torches	Concave mirrors reflect the light inward to one focal point and they are used to focus light.
