The magnifying power of a compound microscope is high if
both eye-piece and objective have short focal lengths
both objective and eye-piece have long focal lengths
the objective has a long focal length and eye-piece has a short focal length
the objective has a short focal length and eye-piece has a short focal length
A
both objective and eye-piece have long focal lengths
B
the objective has a short focal length and eye-piece has a short focal length

Verified by Toppr
Magnifying power = focal length of objective. focal length of eyepiece
So magnifing power ↑ focal length of↑ objective
magnifing power ↑ focal length of↑ eye piece
So option c is correct.
