Spelling – Identify the one misspelled word among options A–D, or choose “All correct” if every option is correctly spelled. A) Intellectual B) Opportunity C) Efficiency D) Responsibility

Introduction / Context:Some questions contain no error; recognizing correctly spelled high-frequency academic words is just as important as spotting mistakes. If all options are correct, “All correct” is the right choice.

Given Data / Assumptions:

• Words: Intellectual, Opportunity, Efficiency, Responsibility.
• All are common in formal writing and are often misspelled due to doubled consonants or vowel clusters.

Concept / Approach:Check hallmark features: “opportunity” has double “p”, not opurtunity; “efficiency” has double “f” and “cie” sequence; “responsibility” keeps “-sibil-”; “intellectual” doubles “l” in the middle. Each presented form matches the standard dictionary spelling.

Step-by-Step Solution:

Verification / Alternative check:Common misspellings would be opurtunity, efficency, responsiblity, intlectual. None appear here. Dictionary check confirms all four as standard.

Why Other Options Are Wrong:There is no wrong spelling here; hence the correct choice is “All correct”.

Common Pitfalls:Second-guessing yourself and inventing an error where none exists. Trust morphological chunks and known doubles.

Final Answer:All correct
