A data driven machine is one that executes an instruction if the needed data is available. The physical ordering of the code listing does not dictate the course of execution. Consider the following pseudo-code:

(A) Multiply E by 0.5 to get F
(B) Add A and B to get E
(C) Add B with 0.5 to get D
(D) Add E and F to get G
(E) Add A with 10.5 to get C

Assume A, B, C are already assigned values and the desired output is G. Which of the following sequence of execution is valid?
(A) B, C, D, A, E
(B) C, B, E, A, D
(C) A, B, C, D, E
(D) E, D, C, B, A
