In each of the following questions, the second group of letters is formed from the first using a specific alphabetical transformation. Apply the same pattern to the third group and find the correct option that completes the analogy.

QDXM : SFYN :: UIOZ : ?

The correct option is WKPA.

Let us analyze the pattern used in the alphabetical transformation between the first group of letters, QDXM, and the second group, SFYN.

First, consider the alphabetical positions of each letter in the English alphabet:
Q = 17, D = 4, X = 24, M = 13
S = 19, F = 6, Y = 25, N = 14

Now, let us examine the transformation step-by-step for each letter position:

1. First letter: Q (17) to S (19)
Pattern: +2 (17 + 2 = 19)

2. Second letter: D (4) to F (6)
Pattern: +2 (4 + 2 = 6)

3. Third letter: X (24) to Y (25)
Pattern: +1 (24 + 1 = 25)

4. Fourth letter: M (13) to N (14)
Pattern: +1 (13 + 1 = 14)

Thus, the rule applied to the letters from left to right is: +2, +2, +1, +1.

Now, apply this exact same transformation pattern to the third group of letters, UIOZ:

Alphabetical positions of UIOZ:
U = 21, I = 9, O = 15, Z = 26

1. First letter: U (21) + 2 = 23, which corresponds to W.
2. Second letter: I (9) + 2 = 11, which corresponds to K.
3. Third letter: O (15) + 1 = 16, which corresponds to P.
4. Fourth letter: Z (26) + 1 = 27 (wrapping around the alphabet: 27 - 26 = 1), which corresponds to A.

Combining these letters together gives WKPA.
