A sentence has been given in Active/Passive Voice. Out of the four given alternatives, select the one which best expresses the same sentence in Passive/Active Voice.
Who burned the food?
Active Voice – Here, the subject performs the action. There is a simple relationship between the doer of the action and the verb.
Example : She is eating a sandwich.
Passive Voice - Here, the subject receives the action. More importance is given to the action (and not the subject)
Example : A sandwich is being eaten by her.
When we want to change interrogative sentences (questions) from active to passive, we need to be mindful of the following rules:
Example :
Active Voice – What were you taking?
Passive Voice – What was being taken by you?
Example :
Active Voice – Has she invited Rani?
Passive Voice – Has Rani been invited by her?
Example :
Active Voice – Who is eating the cake?
Passive Voice – The cake is being eaten by whom?
Understanding these points, we can now change the given sentence from Active to Passive Voice:
Passive Voice : By whom was the food burned?
Thus, the correct answer is option 3.
