Step 1: Recall the background of Fundamental Duties.
Fundamental Duties were not part of the original Constitution and were added later on a committee's recommendation.
Step 2: Identify the committee.
The Swaran Singh Committee, set up in 1976, recommended adding a list of duties for citizens, which were then inserted through the 42nd Constitutional Amendment.
Step 3: Eliminate the other names.
Ajit Kumar Committee, Bhurelal Committee and Srikrishna Committee dealt with entirely different subjects, not Fundamental Duties.
