Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The power of the lens, $P = \frac{1}{f}$ , where $f$ is the focal length.
Hence the power of the lens is larger if its focal length is smaller.
Also the power of a lens is its ability to converge or diverge the rays of light.
