Find which graph goes to each pole

The plot presented is a Root Locus diagram illustrating the paths that poles of the closed-loop system will take in the s-plane as a system parameter is varied. The diagram shows:
- A large circle intersecting the imaginary axis at \( \text{±j1} \) and the real axis between \( -0.5 \) and \( -3.5 \).
- Key points marked as A, B, C, and D around the circle.
**Figure 1. Root Locus for Question 1**
2. **Match each step response below to its corresponding pole location (A, B, C, D) identified on the Root Locus plot in Figure 1.**
The step response graph displayed below shows the system's response to a unit step input over time with amplitude on the y-axis and time (in seconds) on the x-axis. The initial overshoot and settling time are reflective of the damping and natural frequency characteristics of the system's poles.

- **Axis Labels:**
- Y-axis: Amplitude ranging from 0 to 1.4.
- X-axis: Time (sec) ranging from 0 to 14.
**Choose the pole location (A, B, C, or D) on the root locus plot (Figure 1) that corresponds to this step response:**
_______________
**Instructions:**
Look at the damping characteristics and settling time reflected in the step response and associate them with the likely characteristics of the poles in the root locus (damping ratio and natural frequency). An understanding of standard second-order system responses in relation to pole locations in the s-plane is necessary to determine the correct answer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe36fb7f7-6381-4add-b52b-9085dfd27844%2F158e21d2-7b40-40cb-86c7-afeaf6e84a56%2F2m92kjj_processed.jpeg&w=3840&q=75)

#### Graph Descriptions:
1. **First Graph: Step Response**
- **x-axis**: Time (sec) ranging from 0 to 14.
- **y-axis**: Amplitude ranging from 0 to 1.4.
- **Description**: The response starts at amplitude 0, has a slight overshoot just above 1.2, then settles just below 1.2 and continues with a slight upward trend after about 5 seconds.
**Question**: Choose the pole location (A, B, C, or D) on the root locus plot (fig. 1) that corresponds to this step response:
________________________
2. **Second Graph: Step Response**
- **x-axis**: Time (sec) ranging from 0 to 14.
- **y-axis**: Amplitude ranging from 0 to 1.4.
- **Description**: The response starts at amplitude 0, rises quickly to around 1.2 without overshoot, and stabilizes around 1.2 after approximately 2 seconds.
**Question**: Choose the pole location (A, B, C, or D) on the root locus plot (fig. 1) that corresponds to this step response:
________________________
3. **Third Graph: Step Response**
- **x-axis**: Time (sec) ranging from 0 to 14.
- **y-axis**: Amplitude ranging from 0 to 1.
- **Description**: The response starts at amplitude 0 and smoothly increases, gradually approaching but not quite reaching 1 within the observed time range.
**Question**: Choose the pole location (A, B, C, or D) on the root locus plot (fig. 1) that corresponds to this step response:
________________________
These graphs represent different step responses of a control system. The task is to correlate these responses with specific pole locations on a root locus plot (referred to as fig. 1).
