The correct answer is D. All of the mentioned.
An agent is a system that can perceive its environment through sensors and act upon that environment through actuators. It can take input from the surroundings and use its intelligence to perform the desired operations. A line following robot is an example of an agent. It can perceive its environment through sensors, such as cameras and infrared sensors, and act upon that environment by moving its wheels. It can also take input from the surroundings, such as the line it is following, and use its intelligence to determine how to move.
Here is a more detailed explanation of each option:
- Option A: Perceives its environment through sensors and acting upon that environment through actuators. This is a key characteristic of an agent. It can sense its environment through sensors, such as cameras, microphones, and touch sensors, and it can act upon that environment through actuators, such as motors, speakers, and lights.
- Option B: Takes input from the surroundings and uses its intelligence and performs the desired operations. This is another key characteristic of an agent. It can take input from the surroundings, such as from sensors, and it can use its intelligence to perform the desired operations.
- Option C: A embedded program controlling line following robot. This is an example of an agent. A line following robot can perceive its environment through sensors, such as cameras and infrared sensors, and act upon that environment by moving its wheels. It can also take input from the surroundings, such as the line it is following, and use its intelligence to determine how to move.
In conclusion, the correct answer is D. All of the mentioned. An agent is a system that can perceive its environment through sensors and act upon that environment through actuators. It can take input from the surroundings and use its intelligence to perform the desired operations. A line following robot is an example of an agent.
