The correct answer is: A. rises slowly.
A feedback system is a system that uses feedback to control its output. The feedback can be positive or negative. Positive feedback amplifies the output, while negative feedback reduces the output.
In a feedback system, the transient response is the response of the system to a sudden change in the input. The transient response is usually divided into two parts: the rise time and the settling time. The rise time is the time it takes for the output to reach its final value, and the settling time is the time it takes for the output to reach a steady-state value.
In a feedback system with negative feedback, the rise time is usually longer than the rise time of a system without feedback. This is because the negative feedback reduces the amplitude of the output, which makes it take longer for the output to reach its final value.
The settling time is also usually longer in a feedback system with negative feedback. This is because the negative feedback reduces the amplitude of the output, which makes it take longer for the output to reach a steady-state value.
In conclusion, the transient response of a feedback system with negative feedback is usually slower than the transient response of a system without feedback.
