💡 Analysis & Explanation
Pattern Identification ▼
Let us analyze the positional difference between the corresponding letters of each pair in the English alphabet.
Option Analysis ▼
For NO-IJ, N(14)-I(9) is -5 and O(15)-J(10) is -5. For FG-AB, F(6)-A(1) is -5 and G(7)-B(2) is -5. For JK-EF, J(10)-E(5) is -5 and K(11)-F(6) is -5.
Odd One Out ▼
For PK-MJ, P(16)-M(13) is -3 and K(11)-J(10) is -1. This does not follow the -5 difference pattern shared by the others.
Conclusion ▼
Therefore, PK-MJ is the odd one out.
