Select the most appropriate option that expresses the given sentence in active voice.
The door was opened by Samira when the fire was reported by Mithali.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Samira opened the door when Mithali reported the fire.
The original sentence is in passive voice with two actions:
'The door was opened by Samira'
'the fire was reported by Mithali.'
To convert it into active voice, the doers (Samira and Mithali) become the subjects performing the actions.
Option 4 correctly puts both actions in active voice with proper past tense verbs and maintains the original meaning and sequence.
Why the other options are incorrect:
Option 1 changes the tense of 'reports' to present, which doesn't match the original past tense.
Option 2 keeps part of the sentence in passive ('fire was being reported'), so it is not fully active voice.
Option 3 changes the meaning by separating the two actions with 'and' instead of showing the time relationship 'when.'
