AQLZ is related to SIDR in a certain way based on the English alphabetical order. In the same way, CPDV is related to UHVN. To which of the following is EBRY related, following the same logic?

The correct answer is WTJQ.

Let us analyze the relationship between the letter clusters based on the positions of the letters in the standard English alphabetical order:

1. First Pair: AQLZ to SIDR
Let us find the position of each letter in the alphabet:
- A = 1, Q = 17, L = 12, Z = 26
- S = 19, I = 9, D = 4, R = 18

Now, let us examine the pattern between the corresponding position values:
- 1st letter: A (1) + 18 = 19 (S)
- 2nd letter: Q (17) - 8 = 9 (I)
- 3rd letter: L (12) - 8 = 4 (D)
- 4th letter: Z (26) - 8 = 18 (R)

2. Second Pair: CPDV to UHVN
Let us verify the pattern using the second given pair:
- C = 3, P = 16, D = 4, V = 22
- U = 21, H = 8, V = 22, N = 14

Applying the same letter shifts:
- 1st letter: C (3) + 18 = 21 (U)
- 2nd letter: P (16) - 8 = 8 (H)
- 3rd letter: D (4) - 8 = -4 ≡ 22 (V) (in cyclic alphabet order: 4 + 26 - 8 = 22)
- 4th letter: V (22) - 8 = 14 (N)

3. Applying the same logic to EBRY:
Let us find the position of each letter in EBRY:
- E = 5, B = 2, R = 18, Y = 25

Now apply the logic (+18 to the 1st letter, -8 to the remaining letters):
- 1st letter: E (5) + 18 = 23 (W)
- 2nd letter: B (2) - 8 = -6 ≡ 20 (T) (in cyclic alphabet order: 2 + 26 - 8 = 20)
- 3rd letter: R (18) - 8 = 10 (J)
- 4th letter: Y (25) - 8 = 17 (Q)

Combining the resulting letters gives WTJQ.
