To solve this logical reasoning question, we need to identify the pattern among the given pairs of letters and determine which group breaks this pattern. Let's analyze each option.
- Consider the pair CE.
- C is the 3rd letter, and E is the 5th letter in the alphabetical order.
- The difference between E and C is 2.
- Consider the pair IK.
- I is the 9th letter, and K is the 11th letter in the alphabetical order.
- The difference between K and I is 2.
- Consider the pair SV.
- S is the 19th letter, and V is the 22nd letter in the alphabetical order.
- The difference between V and S is 3.
- Consider the pair FH.
- F is the 6th letter, and H is the 8th letter in the alphabetical order.
- The difference between H and F is 2.
- Consider the pair UW.
- U is the 21st letter, and W is the 23rd letter in the alphabetical order.
- The difference between W and U is 2.
From this analysis, we can observe that all pairs except SV have a difference of 2 between their letters. The pair SV has a difference of 3, which makes it the odd one out.
Therefore, the odd group of letters is SV.
