Question:
Assuming you have two threads, A and B with access patterns for A: LW R1, 0(R5); SW R3, 8(R0) and access patterns for B: SW R7, 8(R0); SW R8, 0(R9); LW R9, 12(R0), which of the following is a sequentially consistant execution order? 

Choices:

A. LW R1, 0(R5); SW R3, 8(R0); LW R9, 12(R0); SW R7, 8(R0); SW R8, 0(R9)

B. LW R1, 0(R5); SW R7, 8(R0); SW R8, 0(R9); SW R3, 8(R0); LW R9, 12(R0)

C. SW R7, 8(R0); SW R8, 0(R9); LW R9, 12(R0); SW R3, 8(R0); LW R1, 0(R5)

D. SW R3, 8(R0); SW R7, 8(R0); SW R8, 0(R9); LW R9, 12(R0); LW R1, 0(R5)
