问题 Operation research is a scientific method of providing executive department with a quantitative basis for decisions______the operations under their control.

选项 A、regarding
B、as to
C、on
D、considering

答案 A

解析 regarding"关于"。as to"关于，至于"，用在此处不合适；decision on"对……作出的决定"，不合句意；considering"考虑到，鉴于"。题句意：运筹学是一种科学方法，它为执行部门对其掌管下的各种活动作决定时提供数量根据。
