Select the option that expresses the given sentence in passive voice.
Mrs. Leela opened the window.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. The window was opened by Mrs. Leela.
The original sentence is in simple past tense: Mrs. Leela opened the window.
To change it to passive voice, the object (the window) becomes the subject, and the verb changes to the past tense passive form: was opened.
Option 1 correctly uses the simple past passive structure: 'was opened.'
Option 2 ('was being opened') is past continuous passive, which changes the tense and meaning.
Option 3 ('is opened') is present simple passive, changing the tense.
Option 4 ('is being opened') is present continuous passive, also changing the tense.
