    正确答案: D
    解析: This question is a bit tricky because it lacks the following information: It should include a statement that says whether or not assertions are enabled. If they are indeed enabled, the 
    correction answer is C. but if they are not, the correct answer is A. Assertions are not enabled by default so if the question is not changed, the most logical answer is A.
