SPELLING — Identify the misspelled word among A–D. If all four are correctly spelled, choose E (All correct). Words: A) Quarreled B) Rebellious C) Commission D) Mirraculous

Introduction / Context:
This item mixes standard spellings with a classic doubled-consonant trap. Regional variants (US vs UK) must also be considered for fairness.

Given Data / Assumptions:

• “Quarreled”: US spelling (double r, single l). UK spelling “quarrelled” uses double l—both are acceptable regionally.
• “Rebellious”: correct (double l, suffix -ious).
• “Commission”: correct (double m + double s).
• “Mirraculous”: incorrect; correct is “miraculous.”

Concept / Approach:
We must avoid penalizing acceptable regional variants. “Quarreled” is correct in American English. The truly incorrect form is “Mirraculous,” which inserts an extra “r” and misrepresents the Latin root “miraculum.”

Step-by-Step Solution:
1) Validate A as a legitimate US variant.2) Confirm B and C follow standard doubling patterns.3) Identify D’s incorrect internal consonant sequence.

Verification / Alternative check:
Compare to base form “miracle” (m-i-r-a-c-l-e). The adjective is “miraculous” (m-i-r-a-c-u-l-o-u-s).

Why Other Options Are Wrong:
A, B, C: Correct spellings (A is regionally correct).E: Not applicable; one word is incorrect.

Common Pitfalls:
Assuming “Quarreled” must have double l in all varieties. Recognize accepted regional standards.

Final Answer:
Mirraculous → correct spelling is “miraculous”
