Transform the following sentence into active voice. The meals have been prepared carefully by the chef.

Explanation

The correct option is (b). To convert passive to active voice, we make the agent (introduced by “by”) the subject and change the verb to match the tense. The passive sentence is in Present Perfect passive: “have been prepared”. The corresponding active voice is Present Perfect active: “has/have prepared”. Structure used: Passive voice (Present Perfect): Object + have/has been + V3 + by + Subject. Active voice (Present Perfect): Subject + have/has + V3 + Object. Step-by-step conversion: Agent: “by the chef” becomes the subject “The chef”. Object: “The meals” becomes the object in active voice. Verb: “have been prepared” becomes “has prepared” because “chef” is singular, so we use “has”. Adverb: “carefully” remains in the same sense and is placed after the object for clarity. Thus, the correct active sentence is: “The chef has prepared the meals carefully.” Why other options are incorrect: Option A: Incorrect subject-verb agreement (“chef have”). Option C: Incorrect placement and form (“by carefully” is ungrammatical here). Option D: Changes meaning by making “meals” singular (“meal”). So the correct answer is (b) Copyright © 2026 Adda247
