Which option correctly identifies the mirror a car manufacturer should install as a side-view mirror so that the driver receives an upright but reduced image covering the widest possible field of view?
(a) Concave mirror because it converges reflected rays, giving a reduced image
(b) Convex mirror because it diverges reflected rays
(c) Plane mirror because it preserves actual distances and avoids distortion
(d) Concave mirror used with the vehicle inside its focal length to obtain an upright image
