Given below are the two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R). Assertion (A): There is a considerable increase in covalent radius from N to P. However, from As to Bi only a small increase in covalent radius is observed. Reason (R): Covalent and ionic radii in a particular oxidation state increase down the group. Choose the most appropriate answer from the options below:
- A
(A) is false but (R) is true
- B
Both (A) and (R) are true but (R) is not the correct explanation of (A)
- C
(A) is true but (R) is false
- D
Both (A) and (R) are true and (R) is the correct explanation of (A)
