Concept:Each letter in the first group is moved backward by 4 positions to get the corresponding letter in the second group.Explanation:P (16th) becomes L (12th) — subtract 4.Q (17th) becomes M (13th) — subtract 4.R (18th) becomes N (14th) — subtract 4.Apply same rule to GHI:G (7th) minus 4 gives C (3rd).H (8th) minus 4 gives D (4th).I (9th) minus 4 gives E (5th).So the result is CDE.
