Question

Instruction format has the following structure.Instruction number OPCODE destination Source \(1\) and Source \(2\).
\(I_1:\) Div \(R_3 R_1 R_2;\)
\(I_2:\) Sub \(R_5 R_3 R_4;\)
\(I_3:\) Add \(R_3 R_5 R_6;\)
\(I_4:\) Mul \(R_7 R_3 R_8;\)

• A. There is a RAW dependency on \(R_3\) between \(I_1\) and \(I_2\)
• B. There is a RAW dependency on \(R_3\) between \(I_2\) and \(I_3\)
• C. There is a WAW dependency on \(R_3\) between \(I_3\) and \(I_4\)
