• B. parabolic mirrors create blurred images which are common to those images produced by spherical mirrors.
• C. spherical mirrors create sharp, clear images that lack the blurriness which is common to those images produced by parabolic mirrors.
• D. None of these

Answer 1

The correct option is A parabolic mirrors create sharp, clear images that lack the blurriness which is common to those images produced by spherical mirrors.
