The element exhibiting most stable 
oxidation state among the following is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:

Due to the inert pair effect lead 
has the most stable oxidation state. As we move down the group, the stability of lower oxidation state increases. Hence in Pb group, as we move down the stability of +2 state goes on becoming more than +4 state due to inert pair effect.
