Concept:Each group follows a fixed pattern relating the positions of its three letters in the alphabet.Explanation:The rule is: first letter −3 gives the second letter, and second letter +6 gives the third letter.For DAG: D−3=A, A+6=G → follows the rule.For MJP: M−3=J, J+6=P → follows the rule.For GDJ: G−3=D, D+6=J → follows the rule.For RPV: R−3=Oî€ =P, so it does not follow the rule.For TQW: T−3=Q, Q+6=W → follows the rule.Therefore, RPV is the odd one out.Answer:RPV
