D Correct answer
Explanation

Concave mirrors help to produce large image helps doctors to examine body parts and also are used to auto mobile mechanics to produce strong parallel beam of light during night. Concave mirrors are used to focus sunlight to produce heat from solar furnaces.

Mirrors on the outside of the passenger side of the cars often contain a message that says something like. "Objects are closer than they appear." In the other words, the images seen in the mirror, although looking like the objects in other respects, appear to be further away than they actually are, because the images are the smaller than the objects.
What kind of mirror is being used in this case? 

  1. plane mirror

  2. convex mirror

  3. concave mirror

  4. The mirror could be concave or convex.

  5. The mirror could be flat or concave.

B Correct answer
Explanation

Convex mirrors are used in this case.

Since the mirrors are bend outwards, a large range in area to view is covered to see objects behind in cars.
The magnification of the objects is lesser than one for distant objects for convex mirrors. Hence the objects appear farther away than they actually are.
