Question

I am fully convinced of the integrity of my colleagues.

• A. Fully convincing of
• B. Fully convincing about
• C. Fully convincing of
• D. No correction required

Hint:

Remember: "Convinced of" = certainty; "Convincing" = persuading.

Answer 1

The Correct Option is D

1. Option A: wrongly uses "convincing," which implies persuading others.
2. Option B: same error, plus "about" is non-idiomatic here.
3. Option C: repeats the same "convincing" error.
4. Option D: "convinced of" correctly expresses the speaker's own settled belief.

The correct answer is No correction required.
