Choose the best alternatives in place of ? out of the four given alternatives (a), (b), (c), (d).
CEH : IKN :: ? : ?

Options

A. ACD : FHJ
B. CDF : IJK
C. EFH : KMN
D. OQT : UWZ

Explanation

To solve the analogy CEH : IKN :: ? : ?, we need to identify the pattern in the first pair of letters and apply the same pattern to find the missing letters.

### Step-by-Step Solution:

1. **Identify the Pattern**:
- The first set of letters is CEH.
- We need to find out how each letter in CEH relates to the corresponding letter in IKN.
- C to I:
- C is the 3rd letter of the alphabet.
- I is the 9th letter of the alphabet.
- The difference is 9 - 3 = 6.
- E to K:
- E is the 5th letter of the alphabet.
- K is the 11th letter of the alphabet.
- The difference is 11 - 5 = 6.
- H to N:
- H is the 8th letter of the alphabet.
- N is the 14th letter of the alphabet.
- The difference is 14 - 8 = 6.
- Thus, we see that each letter in the first set is increased by 6 to get the corresponding letter in the second set.

2. **Apply the Pattern**:
- Now, we need to find a new set of letters that follows the same pattern. Let's denote the new letters as XYX.
- We need to find letters such that:
- X + 6 = Y
- Y + 6 = Z

3. **Choose the First Letter**:
- Let's choose O as the first letter (O is the 15th letter of the alphabet).
- O + 6 = U (21st letter).
- U + 6 = A (1st letter, considering the alphabet wraps around).

4. **Check the Options**:
- Now we need to check which of the provided options fits this pattern:
- O (15) → U (21)
- Q (17) → W (23)
- T (20) → Z (26)

5. **Final Answer**:
- The letters O, Q, T correspond to U, W, Z respectively, which follows the same pattern as CEH to IKN.
- Therefore, the answer is OQT : UWZ.
