Choose the most suitable option to replace the highlighted part of the sentence: I am confident to pass the examination.
- (a)in passing the exam
- (b)to passing the exam
- (c)of passing the examination
- (d)for passing examination
Answer
Why
Correct — C. The trigger is the adjective confident. When it means sure that something will happen, it takes of + an -ing form or a noun: confident of winning, confident of success.
It can also take a that-clause: I am confident that I will pass.
So 'confident to pass' becomes confident of passing the examination → option (c).
Why the others are wrong
- (a)in passing the exam — Confident in expresses trust in someone or something — confident in her ability, confident in the team. It does not express certainty about an outcome such as passing.
- (b)to passing the exam — To + -ing belongs to phrases like look forward to and be committed to, where 'to' is a preposition. Confident is not followed by 'to' in that way.
- (d)for passing examination — For is not the preposition confident takes for an expected result; that is of. The option also drops the before examination, a singular countable noun that needs a determiner.
Concept
Many adjectives fix the preposition after them. Confident takes of or about before what you are sure of, and in before whom or what you trust.
After a preposition, a verb takes the -ing form: of passing, about winning. That is why all four options here put 'passing' after their preposition.
Two checks decide the item: the right preposition for the meaning, then a complete noun phrase after it — 'the examination', not bare 'examination'.
'Confident enough to + verb' is standard for self-assurance: confident enough to speak up. This sentence is about an expected result, and that sense takes 'of' + -ing or a that-clause.
Key facts
- Confident of (or about) + noun or -ing: sure that something will happen — confident of passing, confident of success.
- Confident + that-clause: I am confident that I will pass.
- Confident in + person or thing: trust — confident in her ability.
- After a preposition, a verb takes the -ing form.

Common traps
- Choosing 'confident in' because it sounds familiar — it expresses trust in someone, not certainty about a result.
- Fixing the preposition but accepting 'passing examination' with no article before a singular countable noun.
