Answer 1

Answer:

D. The 40x objective

Explanation:

Total magnification = 400x

Total magnification= magnification by ocular lens× magnification by objective lens

therefore, magnification by objective lens = Total magnification /magnification by the ocular lens

= 400/10= 40

Hence, the magnification by objective lens = 40x
