Select the correct active form of the given sentence.
How many days were taken by you to paint this picture?

Correct option is A

The correct active voice of the given sentence is (a) How many days did you take to paint this picture?
Rules of conversion (Passive → Active for Interrogatives):
· Identify object/agent: Passive “ were taken by you” → agent = you (subject in active).
· Main verb phrase: were taken (past simple passive of “take”) → active becomes did … take (past simple).
· Interrogative structure in active: (Wh-word) + did + subject + base verb + … ?
· Retain the rest of the complements: to paint this picture stays as is.
Structure:
· Passive voice: Wh-word + was/were + past participle + by + agent + … ?
· How many days were taken by you … ?
· Active voice: Wh-word + did + subject + base verb + … ?
· How many days did you take … ?
Why other options are incorrect:
· (b) Changes meaning (“picture” as subject + “paint you”)—nonsensical.
· (c) Uses present simple (“do you take”) instead of past simple—tense mismatch.
· (d) Uses present perfect (“have you taken”)—tense mismatch with the original were taken (simple past).
