Correct answer: C
Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text. Therefore, vasectomies are the exception among the listed uses. Choices A, B, and D are supported by details in the extract, making them incorrect answers.
