问题补充：

The doctors to operate on the woman because her husband had not given permission.

A. would refuse

B. have refused

C. refuse

D. refused

答案：

A. would refuse

B. have refused

C. refuse

(答案→)D. refused

解析：考察时态。句意：因为她的丈夫不允许，所以医生拒绝给这个女士动手术。根据句中的had not given permission可知这是一个过去完成时，是发生在前面一句之前的事情，故前面的主句使用一般过去时。故D正确。
