  2. B1 and 4
  3. C2,3 and 4
  4. D1, 2 and 3

Correct answer

D. 1, 2 and 3

Step-by-step solution

In case of compound microscope both the eyepiece and the objective of are made up of convex lenses. The focal length of the objective of a telescope is larger than the focal length of its eyepiece. The magnification of a telescope increases with the increase in focal length of its objective since m= f _ o / f _ e while the magnification of microscope decreases with increase in focal length of its objective.
