Assertion (A) : Anything that influence...

Assertion (A) : Anything that influences of the valence electorns will affect the chemistry of the element. So, the nuclear molar mass does not affect the valence shell.
Reason (R ) : Nucleus contains protons and neutrons, whereas protons i.e. nuclear charge affects the valence shell but neutrons doe not.

A

If both Assertion (A) and (R ) are correct and Reason (R ) is the correct explanation of Assertion (A).

B

If both (A) and (R ) are correct but (R ) is not the correct explanation for (A).
