Given below are two statements: one is labeled as Assertion (A) and the other is labelled as Reason (R) . Assertion (A): In aqueous solutions Cr 2+ is reducing while Mn 3+ is oxidising in nature. Reason (R): Extra stability to half filled electronic configuration is observed than incompletely filled electronic configuration. In the light of the above statements, choose the most appropriate answer from the options given below :

1. Both (A) and (R) are true and (R) is the correct explanation of (A) .
2. (A) is true but (R) is false.
3. Both (A) and (R) are true but (R) is not the correct explanation of (A) .
4. (A) is false but (R) is true.

Correct answer: Both (A) and (R) are true and (R) is the correct explanation of (A) .
