Five-letter patterned blocks with alternating +3 and −2 streams: AYBZC, DWEXF, GUHVI, JSKTL, ? Identify the next block by following each character-position’s rule.

Introduction / Context:
Each block has five letters, and every position within the block (1st through 5th) follows its own independent alphabetical rule across blocks. Two of these rules move forward by +3, and two move backward by −2, creating a braided pattern.

Given Data / Assumptions:

• Blocks: AYBZC, DWEXF, GUHVI, JSKTL, ?
• Alphabet indices A=1 … Z=26.
• We track each of the five positions across blocks separately.

Concept / Approach:
Write the five vertical streams: 1st letters, 2nd letters, 3rd, 4th, and 5th. Identify the step for each stream, then apply it to the last known block to generate the next block.

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

• MQORN / NQMOR / QMONR disturb at least one of the vertical streams by swapping letters into the wrong positions.

Common Pitfalls:
Trying to spot a single across-the-line rule inside each block instead of tracking columns through successive blocks.

Final Answer:
