Step 1: Check who is never matched
We need to find the person whose answer key was not copied by anyone.
Jassi’s answers: b d d c b d a c a b
Compare with others: - Munna ≠ Jassi (only Munna is original) - Chinky, Lucky, Arun, Ritesh etc. — None exactly match Jassi.
Conclusion: No one used Jassi’s answers as base.
