Answer:
- C.
Step-by-step explanation:
In this exercise you have to choose the correct pronoun.
The sentence says El médico ___ examina la garganta pero yo no ___ examino la garganta. So the best option to complete the blank is letter "C" because we require a singular second person pronoun like "le" and in the second sentence we requiere the first person singular pronoun "me".
So the correct version would be El médico le examina la garganta pero yo no me examino la garganta.
