Consider the following instruction sequence:
$$
\begin{aligned}
&\text{I}_1: \text{R}_1=100\\
&\text{I}_2: \text{R}_1=\text{R}_2+\text{R}_4\\
&\text{I}_3: \text{R}_2=\text{R}_4-25\\
&\text{I}_4: \text{R}_4=\text{R}_1+\text{R}_3\\
&\text{I}_5: \text{R}_1=\text{R}_1+30\\
\end{aligned}
$$
The number of Read-After-Write (RAW) dependencies, Write-After-Read(WAR) dependencies, and Write-After-Write (WAW) dependencies in the above sequence of instructions are, $\text{A, B, C}$ respectively, then which of the following is true?
- $\mathrm{B}=4$
- $\mathrm{A}=4$
- $\mathrm{A}=2$
- $\mathrm{C}=2$
