A business plan should be a strategic outline of you are going to do why and how you are

问题补充：

A business plan should be a strategic outline of you are going to do, why and how you are going to do it.

A. what

B. which

C. how

D. that

答案：

(答案→)A. what

B. which

C. how

D. that

解析：考查宾语从句。本句中what引导宾语从句what you are going to do作为介词of的宾语，并在句中作为动词do的宾语。How在句中不能做宾语，that在宾语从句中不充当任何成分，只起引导作用。Which是指特定范围之内的某一个。故A正确。
