问题补充：

A. should have taken
B. could have taken
C. needn’t have taken
D. mustn’t have taken
答案：
A. should have taken
B. could have taken
(答案→)C. needn’t have taken
D. mustn’t have taken
解析：考查情态动词用法。Should have done本应该做某事，实际上却未做；could have done本可以做某事，实际上却未做；needn’t have done本不必做某事，实际上却做了；句意：昨天的天气结果是很好，我本不应该带着雨伞的。根据句意说明Ｃ正确。
