Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): There is a considerable increase in covalent radius from \( \text{N} \) to \( \text{P} \). However from \( \text{As} \) to \( \text{Bi} \) only a small Increase in covalent radius is observed.
Assertion (R): Covalent and ionic radii in a particular oxidation state increases down the group.
In the light of the above statements, choose the most appropriate answer from the options given below:
