What is an AI ‘agent’? A. Takes input from the surroundings and uses its intelligence and performs the desired operations B. An embedded program controlling line following robot C. Perceives its environment through sensors and acting upon that environment through actuators D. All of the mentioned

The correct answer is D. All of the mentioned.

An AI 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 uses its intelligence to perform the desired operations.

For example, a line following robot is an AI agent that can perceive its environment through sensors (such as cameras or infrared sensors) and act upon that environment through actuators (such as motors). The robot can use its intelligence to follow a line on the ground.

Another example of an AI agent is a self-driving car. The car can perceive its environment through sensors (such as cameras, radar, and lidar) and act upon that environment through actuators (such as steering, braking, and acceleration). The car can use its intelligence to navigate safely through traffic.

AI agents are used in a variety of applications, including robotics, self-driving cars, and healthcare.
