Diaphragm is placed nearer to the eyepiece. So I think option B is wrong.

You are correct @Angel.

Nabin said: 4 years ago

Here, option B should be" the diaphragm is placed between the eyepiece and objective but farther from later".

Allah Nawaz said: 4 years ago

B is not the correct one. Because nearer to Eye piece then it should be nearer to earlier.

AHMAD said: 4 years ago

Yes, I too agree that Option B is incorrect.
