Ok thank you.

You're welcome.

The correct option to complete the sentence is "who".

To determine the correct answer, we need to understand the role of the pronoun in the sentence. In this case, the pronoun is used to identify the person who performed the action of operating on the patient. We are referring to the surgeon as a person, not an object or thing, so we need to use the pronoun "who".

Another way to determine the correct answer is to rephrase the sentence and see if it still makes sense. We can rephrase the sentence as follows: "The surgeon has a great reputation. He operated on the patient." Here, we can clearly see that the pronoun "he" is used to refer to the surgeon, so the correct pronoun to use in the original sentence is "who".
