Solution

The correct option is B Using lens of smaller focal length

Simple microscope is nothing but a magnifying glass.

We have the formula for power of lens P = 1/f

From this we can observe that magnifying power is inversely proportional to the focal length

Therefore, the smaller the focal length, the higher the magnifying power.

Therefore the correct answer is B
