Answer #1

Magnification of a microscope is the ability to magnify the specimen or object under study. Magnification of a microscope is the product of magnification of objective lens and magnification of eyepiece lens.

Magnification = magnification of objective lens x magnification of eyepiece lens

M = me x mo

Here in the question the object is magnified 100x larger

M = 100

The magnification of ocular/ eyepiece is 10 x

me = 10

So, the objective magnification is,

mo= M / me= 100 /10

= 10

The objective is in 10 x alignment

Other options are incorrect.

Option C is the answer.

10X is the answer.
