问题补充：
Would it be possible for me to meet with you and discuss the matter?
A. on your comfort
B. at your service
C. at your ease
D. at your convenience
答案：
A. on your comfort
B. at your service
C. at your ease
(答案→)D. at your convenience
解析：
试题分析:考查固定短语。从语义可知说话人想见对方，应该找人家方便的时候，而at your service意思是“听您吩咐”； at your ease“无拘无束”；at your convenience“在你方便的时候”。所以D选择正确。句意：我有没有可能在你方便的时候见见你，讨论讨论这件事呢？
