A lens with large focal length have less power. i.e., P propto (1/f) or f propto (1/P)

Q. Statement I Power of a lens is defined as $p = 1/ f$ , $f =$ focal length.
Statement II A lens of a high power has large focal length.

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.

Both Statement I and Statement II are correct but Statement II is not the correct explanation of Statement I.

Statement I is correct but Statement II is incorrect.

Statement I is incorrect but Statement II is correct.

A lens with large focal length have less power.
i.e., $P \propto \frac{1}{f}$
or $f \propto \frac{1}{P}$
