**Block Diagram Description** This block diagram represents a control system. Below is an explanation of each component and the flow of signals: 1. **Input Signal (R[s])**: The system receives an input signal denoted as R(s). 2. **Summation Block (Σ)**: This block sums two inputs. It takes the input signal R(s) and subtracts the feedback signal. The output is denoted as E(s). 3. **Controller (Gc[s])**: The output of the summation block E(s) is fed into the controller block Gc(s), which processes the error signal. 4. **Process Block (G[s])**: The controller output is passed through the process block G(s), which represents the system's dynamics. 5. **Output Signal (Y[s])**: The final output of the system after processing through G(s) is denoted as Y(s). 6. **Feedback Loop**: The output Y(s) is fed back into the summation block to close the loop, allowing the system to adjust based on the output. **Overall Functionality**: The diagram illustrates a feedback control system where the output is continuously compared with the input, and adjustments are made to minimize error. This is a typical representation of systems used in control engineering to regulate processes and maintain desired outputs.

Given the transfer function \( G[s] = \frac{(s-1)}{(s+1)(s+2)} \), select a controller to stabilize the closed-loop system. **Options for \( G_c[s] \):** (a) \( G_c[s] = \frac{(s+2)}{(s-1)} \) (b) \( G_c[s] = \frac{(s+1)}{(s-1)} \) (c) \( G_c[s] = \frac{4(s+1)}{(s+2)} \) (d) \( G_c[s] = \frac{(s+1)}{(s+3)} \) Analyze each controller option to determine which one will stabilize the system by considering the poles and zeros in the open-loop transfer function.
