313426 Assertion :
Zinc is placed in 12th group of the periodic table, but is not a d-block element.
Reason :
Zinc has completely filled 3d orbitals in its +2 oxidation state.

1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.

2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
