Concept:Each group follows a pattern: second letter is 3 positions ahead of the first, and the third letter is the alphabetically opposite of the second letter.Explanation:Assign positions: A=1,B=2,…,Z=26. Opposite letters have positions adding to 27.Check each option:FIR: F(6)+3=I(9), and opposite of I is R(18). Pattern holds.JMN: J(10)+3=M(13), and opposite of M is N(14). Pattern holds.BEV: B(2)+3=E(5), and opposite of E is V(22). Pattern holds.UXZ: U(21)+3=X(24), but opposite of X is C(3), not Z(26). Pattern fails.QTG: Q(17)+3=T(20), and opposite of T is G(7). Pattern holds.Thus, only UXZ is the odd one out.Answer:D. UXZ
