Text Solution
Verified by ExpertsThe correct answer is:
B
As we know stability of carbanion is directly proportional to -M and -I effect i.e. E.W. groups
Stability of anions 
In the given compounds structure 
will be least stable because 
group is preset at pare position as it is an electron releasing group. In rest compounds -I effect observed and follows the order- 
Stability orderofthe compound is S
