The correct answer is B. AI system.
An AI system is a computer system that can mimic the capabilities of a human brain. It can learn, reason, and make decisions. AI systems are built in such a way that humans have to supply the inputs and interpret the outputs. This is because AI systems are not yet able to understand the world in the same way that humans do.
A sensor is a device that detects and responds to changes in its environment. Sensors are used to collect data that can be used by AI systems. For example, a sensor can be used to detect the presence of a person in a room. This data can then be used by an AI system to make decisions about how to interact with the person.
An actuator is a device that is used to control a machine or system. Actuators are used to carry out the instructions of an AI system. For example, an actuator can be used to open a door. This instruction can be given by an AI system that has determined that the door needs to be opened.
Agents are entities that can act autonomously in an environment. Agents are often used in AI systems to control robots or other machines. Agents can be programmed to follow a set of rules or to learn from their environment.
In conclusion, the correct answer is B. AI system. AI systems are built in such a way that humans have to supply the inputs and interpret the outputs. This is because AI systems are not yet able to understand the world in the same way that humans do.
