问题 My patients, if______ the opportunity, would freely converse about their problems whilst ______ in my waiting room.

选项 A、giving, sitting
B、giving, sat
C、given, sat
D、given, sitting

答案 D

解析省略用法题。状语从句如果从句主语和主句主语相同则可省略主语和系动词，本题if given the opportunity=if they were given the opportunity，而whilst sitting=whilst they were sitting，故D正确。
