(A) If both assertion and reason are true and reason is the correct explanation of assertion. (B) If both assertion and reason are true but reason is not the correct explanation of assertion. (C) If assertion is true but reason is false. (D) If both assertion and reason are false.

Greater stability of K2[Ni(EDTA)] is due to greater number of chelate (rings) formed by EDTA as compared to C2O2-4.

Q. Assertion : $K_{2} [N i (E D T A)]$ is more stable than $K_{3} [A l (C_{2} O_{4})_{3}]$ .
Reason : Ni is a transition element while Al is a non transition element.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

Greater stability of $K_{2} [N i (E D T A)]$ is due to greater number of chelate (rings) formed by $E D T A$ as compared to $C_{2} O_{4}^{2 -}$ .
