Parts of the following sentence have been given as options. Select the option that contains an adverb-usage error.
Benjamin and Lucas gently volunteered for the disaster management task.

Correct option is D

Option (d) gently volunteered contains an adverb-usage error.
Explanation:
The verb “volunteer” refers to offering help or service willingly, which is already a gentle action. Using “gently” is inappropriate because it typically refers to physical actions, not intent or decision.
Correct sentence:
Benjamin and Lucas volunteered for the disaster management task.
Grammatical Rule Used:
Adverbs of manner should logically match the verb. “Gently” is misused here with “volunteered,” which doesn’t describe a physical action needing softness.
✦ Explanation in Hindi:
“Gently” का अर्थ होता है “धीरे से” और यह आमतौर पर शारीरिक क्रियाओं के साथ आता है, जैसे "gently push"। लेकिन “volunteer” एक मानसिक निर्णय है, जिसके लिए यह उपयुक्त नहीं है।
