Explanation:

Let’s break this apart and see which letter-cluster fits.

- First, notice the pattern in each letter’s position.

- WUE: W(23), U(21), E(5)

- XXG: X(24), X(24), G(7)

- YAI: Y(25), A(1), I(9)

- Start of each triplet: W, X, Y, ?

- That’s going up by 1 in the alphabet: W?X?Y?Z

- Second letter: U(21), X(24), A(1). Here's where it gets interesting.

- U?X = +3 (forward in the alphabet)

- X?A = +3? No, wait—X(24) to A(1) wraps around. If you look at it as (24+3=27) but since there are 26 letters, 27 loops back to 1: A.

- Pattern: add 3 each time, and loop around after Z (26).

- U(21) + 3 = X(24)

- X(24) + 3 = [27 = 1] A(1)

- A(1) + 3 = D(4)

- Third letter: E(5), G(7), I(9) — These are going up by 2 each time.

- E?G?I (5+2=7, 7+2=9)

- Next should be I+2=K(11)

Now, applying the pattern:

- First letter: Z

- Second letter: D

- Third letter: K

So, ZDK.

Let’s look at the options:

1. ZDK

2. ZOK

3. ZBH

4. ZAJ

Here’s the thing—Option 1 is the match.

- ZDK is the one that fits the systematic letter shifts we’re seeing.

- Options 2, 3, and 4 don’t fit the +3, +2 growth in order.

- ZOK and ZAJ: their second or third letters don’t follow the +3, +2 rule.

- ZBH: second and third letters don’t fit at all.

Nice work sticking to the facts and logic!
