Select the option that expresses the given sentence in active voice.
The meal was not prepared by us.

Correct option is B

The correct active voice of the sentence is We did not prepare the meal.
Explanation:
· In the passive voice, the object ("the meal") becomes the subject, while the subject ("we") moves to the end.
· To convert to active voice, the original subject ("we") is restored, followed by the verb in the correct tense ("did not prepare").
Grammatical Rule:
· Passive voice: Object + was/were + past participle + by + subject.
· Active voice: Subject + did + base verb + object.
Example:
· Passive: The house was cleaned by her.
· Active: She cleaned the house.
Why other options are incorrect:
· Option (a): Incorrect tense.
· Option (c): Incorrect verb form ("preparing").
· Option (d): Changes meaning by using an affirmative statement.
