When challenged, the man had no answer for his actions.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. No substitution required.
The most appropriate option to substitute the underlined segment in the given sentence is "No substitution required."
The original sentence, "When challenged, the man had no answer for his actions," is grammatically correct and conveys that the man was unable to justify his actions when he was confronted.
The other options—"While challenges," "When to be challenged," and "When in challenge"—are either grammatically incorrect or do not convey the intended meaning as effectively as the original phrasing.
Therefore, no substitution is needed.
