Change the underlined part of the '-ing clause' with 'adjective + to infinitive.'

Namita wasn't ashamed of committing the mistake.

Namita wasn't ashamed to commit the mistake.

The correct answer is Option (3) → Namita wasn't ashamed to commit the mistake.

Explanation:
- In the original sentence, "committing" is a gerund (-ing form) functioning as a noun, serving as the object of the preposition "of" after "ashamed."
- The phrase "to commit" is an adjective phrase modifying "ashamed." It indicates the reason for Namita's lack of shame.
- Therefore, by replacing "committing" with "to commit," we maintain the structure and meaning of the sentence.
