Correct option is C
Option (c) contains an error.
Explanation: The verb "was brought" is in passive voice, but "The peon" is the doer of the action (subject), not the receiver. The correct sentence should be “The peon brought a cup of coffee for Naina.”
The structure “was brought” indicates that the peon received the coffee, which distorts the meaning.
Grammatical rule used: Subject-Verb-Object agreement and proper use of passive voice. Passive voice is used when the subject receives the action, not performs it.
Example: Passive – “A cup of coffee was brought by the peon.” (Here, cup is the subject.)
Grammar Booster:
Avoid passive construction when the subject is the doer.
Use active voice for clarity unless the receiver of the action is more important than the doer.
