MCQ
Given below are two statements: one is labelled as Assertion(A) and the other is labelled as Reason (R).
Assertion(A) : $E^{\circ}$ value for $Mn ^{3+} / Mn ^{2+}$ couple is much more positive than that of $E ^{\circ}$ value for $Cr ^{3+} / Cr ^{2+}$ or $Fe ^{3+} / Fe ^{2+}$.
Reason ( R ) : Mn have very high value of 3rd ionization energy in comparision to Cr and Fe .
In the light of the above statements, choose the most appropriate answer from the options given below:

Reason ( R ) : Mn have very high value of 3rd ionization energy in comparision to Cr and Fe .
In the light of the above statements, choose the most appropriate answer from the options given below:
- ✓Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- BBoth Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).
- CAssertion (A) is true but Reason (R) is false.
- DBoth Assertion (A) and Reason (R) are false
