单选题 Which of the following explanations regarding the high number of Caesarean operations is NOT true?

A、 Some mothers have passed the best age for a natural delivery.
B、 Some mothers have fertility problems.
C、 Some mothers favor the operations of this type.
D、 Some mothers have had surgical operations on their fallopian tubes.

【正确答案】 C

【答案解析】[分析] 是非题型。根据第三段最后一句Most of the mothers were older, had long histories of fertility problems and in some cases had had surgery on the fallopian tubes, all of which made them likely candidates for Caesareans anyway．可知答案是C项。
