Select the most appropriate passive form of the given sentence.
The surgeon successfully operated upon the patient.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. The patient was successfully operated upon by the surgeon.
Explanation:
The given active voice is in the past indefinite.
So, while making the passive voice, the structure will be:
Object + was/were + V3 + by + Subject.
The preposition ‘upon’ after the verb ‘operated’ will be kept as it is.
The correct passive form will be: "The patient was successfully operated upon by the surgeon."
Hence, the chosen option is correct.
