Select One Correct Option from the following: An astronomical telescope has an angular magnification of magnitude 5 for distant objects. The separation between the objective and the eyepiece is 36 cm and the final image is formed at infinity. The focal length $f_{0}$ of the objective and the focal length $f_{e}$ of the eyepiece are
(A) $f_{0}$ = 45 cm, $f_{e}$ = −9 cm
(B) $f_{0}$ = 50 cm, $f_{e}$ = 10 cm
(C) $f_{0}$ = 7.2 cm, $f_{e}$ = 5 cm
(D) $f_{0}$ = 30 cm, $f_{e}$ = 6 cm.
