NOPQ : MLKJ :: HIJK : ?

Options

A. DEFG
B. EFGH
C. FEDC
D. GFED

Explanation

To solve the analogy problem, we need to analyze the first pair of letters and their corresponding transformations to find the pattern.

### Step-by-Step Solution:

1. **Identify the first pair**: The first part of the analogy is "NOPQ" and it corresponds to "MLKJ".

2. **Determine the transformation**:
- N to M: Move 1 letter backward (N → M)
- O to L: Move 3 letters backward (O → N → M → L)
- P to K: Move 5 letters backward (P → O → N → M → L → K)
- Q to J: Move 7 letters backward (Q → P → O → N → M → L → K → J)

3. **Establish the pattern**: The transformation involves moving backward through the alphabet by increasing odd numbers:
- 1 letter backward for the first letter
- 3 letters backward for the second letter
- 5 letters backward for the third letter
- 7 letters backward for the fourth letter

4. **Apply the same transformation to the second part "HIJK"**:
- H to G: Move 1 letter backward (H → G)
- I to F: Move 3 letters backward (I → H → G → F)
- J to E: Move 5 letters backward (J → I → H → G → F → E)
- K to D: Move 7 letters backward (K → J → I → H → G → F → E → D)

5. **Compile the results**: After applying the transformations, we find:
- H → G
- I → F
- J → E
- K → D

6. **Final result**: The resulting letters from "HIJK" after applying the transformations are "GFED".

### Conclusion:
The answer to the analogy "HIJK : ?" is "GFED".
