Text Solution

Verified by Experts
The correct answer is:
C

Have higher enthalpy of atomization because of the involvement of greater number of valence electrons in the bonding. So their melting points are higher.

They show catalytic activity due to their variable oxidation states.

Energy of ns and (n –1) d orbitals are nearly same and thus electrons of ns and (n–1)d orbitals can take part in bonding.

Only heavier p-block elements show inert pair effect, not d-block elements.
