Key Points

To change a sentence from active voice to passive voice, we need to follow these rules:

• Identify the subject, verb and object of the active sentence.
• Make the object of the active sentence the subject of the passive sentence.
• Use a form of the verb be with the past participle of the main verb to form the passive verb.
• Add by and the subject of the active sentence after the passive verb, unless the subject is unknown or unimportant.
• In this question, the active sentence is: Mr. Mehta manages a big industrial empire.
• The subject is Mr. Mehta, the verb is manages, and the object is a big industrial empire.
• To change it into passive voice, we need to:
  • Make the object (a big industrial empire) the subject of the passive sentence.
  • Use a form of be (is) with the past participle of manage (managed) to form the passive verb (is managed).
  • Add by and the subject (Mr. Mehta) after the passive verb.
• The passive sentence is:
  • A big industrial empire is managed by Mr. Mehta.

Therefore, the correct answer is (b).
