The passive form of the sentence, "Who did the work?" is .....
ক) By whom the work was done?
খ) Whom had the work done by?
গ) By whom was the work done?
ঘ) Who was the work done?

ব্যাখ্যা

For interrogative sentences starting with "Who", the passive starts with "By whom". The correct structure is: By whom + auxiliary verb + object (as subject) + past participle.

১. Option (ক) is incorrect because the auxiliary "was" should come before the subject in a question.
২. Option (খ) incorrectly uses "had" and has a flawed prepositional placement.
৩. In "By whom was the work done?", the word order follows the standard interrogative passive rule.
