Text Solution

Verified by Experts
The correct answer is:
B

Metallic nature increases from top to bottom due to decrease in electronegativity. Also, ionisation potential values decrease from top to bottom due to increase in atomic radius of element. However, stability of +2 oxidation state increases and +4 oxidation state decreases from top to bottom due to inert pair effect
