The structure of the simple instruction set MIPS microprocessor is shown in the following figure. Which description is correct about the valid data path for the execution of the lw instruction?
下图为简单指令集MIPS微处理器的结构框图，试问执行lw指令时关于有效数据通路描述正确的是？

A、Paths marked with C,D,E,K,J,P,L,W,S,T are valid
标注为C,D,E,K,J,P,L,W,S,T的通路有效
B、Paths marked with C,D,F,K,U,P,I,L,W,S,T are valid
标注为C,D,F,K,U,P,I,L,W,S,T的通路有效 
C、Paths marked with C,D,E,K,J,P,L,N,O,T are valid
标注为C,D,E,K,J,P,L,N,O,T的通路有效
D、Paths marked with C,E,F,K,J,P,W,V,S,T are valid
标注为C,E,F,K,J,P,W,V,S,T的通路有效
