Great job! Your answers are correct. Here's an explanation of why each answer is correct.

For the first question, the correct answer is A because it correctly uses commas to separate the list of actions: The implant was ruptured, it was removed, the capsule was irrigated.

For the second question, the correct answer is C. It uses a comma to separate the two independent clauses: She was tried on various antibiotics, and an infectious disease specialist was called in to advise on this.

For the third question, the correct answer is A. It correctly uses commas to set off the names: Mrs. Smith came to the hospital accompanied by her husband, Mr. Smith, and their youngest daughter.
