NEET Chemistry Stability of Complexes Assertion Reason Question with Solution

Assertion : K₂[Ni(EDTA)] is more stable than K₃[Al(C₂O₄)₃]. Reason : Ni is a transition element while Al is a non-transition element.

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.
