Step 1: Identify Munna’s pattern
Munna got exactly 9 out of 10 answers correct. From the final answer key (last row — Sastry), we compare Munna’s row: Sastry:b , d , d , c , b , d , a , c , a , b
Munna: b , d , d , c , b , d , a , c , b , b] Only mismatch is at Q9 ⇒ Munna changed this intentionally (as per passage).
Step 2: Find two students who can be jigri to Munna
A student’s answer key is copied from either one or two jigri(s). If two: identical ⇒ copied, else blank. Let’s check whose answers closely match Munna except Q9.
Niran: b d d c b d a c b b (Only Q9 differs from Sastry) ✔️

Therefore, Munna is the jigri of Niran and Praveen.
