A diminished image of an object is to be obtained on a screen \( 1.0 \mathrm{~m} \) away from it. This can be achieved by approximately placing:
\( \mathrm{P} \)
(A) a convex mirror of suitable focal length
W
(B) a concave mirror of suitable focal length
(C) a convex lens of focal length less than \( 0.25 \mathrm{~m} \)
(D) a concave lens of suitable focal length.
