Find the odd letter group from the alternatives given below. Each option contains a 4-letter pattern where the middle letter is repeated. Identify the group that does NOT follow the common consecutive-position pattern seen in the others. (A) ABBC (B) PQQR (C) WYYZ (D) KLLM (E) CDDE

Introduction / Context:
This is an odd-one-out problem based on internal letter sequencing. Many letter-group questions use consecutive alphabet positions with a repeated middle letter. The trick is to check whether the overall pattern is of the form: x, x+1, x+1, x+2 (in terms of alphabet positions). The option that breaks this structure is the odd one out.

Given Data / Assumptions:

• Convert letters to positions: A=1, B=2, ..., Z=26.
• Check whether the sequence of positions follows x, x+1, x+1, x+2.
• The repeated middle letter should be exactly one step after the first letter in the correct pattern.

Concept / Approach:
Most valid options have 1st letter, then the next letter repeated twice, then the following letter. In other words: first letter increases by +1 to the repeated letter, and then the last letter is +1 from that repeated letter.

Step-by-Step Solution:

Verification / Alternative check:
A quick check is to see if the first letter is immediately followed by the repeated letter. In ABBC, A is followed by B. In PQQR, P is followed by Q. In KLLM, K is followed by L. In CDDE, C is followed by D. But in WYYZ, W is not followed by X; it jumps to Y. That confirms WYYZ is the odd one out.

Why Other Options Are Wrong:

Common Pitfalls:
Students often focus only on the repetition (middle letter repeated) and miss the important detail: whether the letters are consecutive. Another pitfall is ignoring the first jump and only checking the last letter. Always confirm the exact step sizes: the first-to-middle jump must be +1 in the standard pattern here.

Final Answer:
WYYZ
