Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

Answer 1

Positional value Table

Let's analyze the pattern for each letter-cluster pair by finding the relationship between the two letters in each pair.

1) NM - PO

Pattern: First letter +2, Second letter +2.

2) SR - UT

Pattern: First letter +2, Second letter +2.

3) UT - WV

Pattern: First letter +2, Second letter +2.

4) NQ - RM

Pattern: First letter +4, Second letter -4.

Options 1, 2, and 3 follow the same pattern where each letter shifts forward by 2 positions.

Option 4 follows a different shifting pattern and does not have consecutive letters within the clusters.

Hence, the correct answer is "Option 4".
