In Galilean telescope, if the powers of an objective and eye lens are respectively \( +1.25 \mathrm{D} \) and \( -20 \mathrm{D} \), then for relaxed vision, the length and magnification will be
(A) \( 21.25 \mathrm{~cm} \) and 16
(B) \( 75 \mathrm{~cm} \) and 16
(C) \( 75 \mathrm{~cm} \) and 20
(D) \( 8.5 \mathrm{~cm} \) and \( 21.25 \)
