The correct answer is Perception, Reasoning, Action, Memory.I remember this because these four are basically what allow an AI agent to function intelligently. Perception is how it senses or gathers information from its environment. Reasoning is how it processes that information and makes decisions. Action is how it responds or does something based on its reasoning. And Memory helps it store past experiences or data so it can learn and improve over time. These four work together to make an AI behave more like a thinking system rather than just following fixed instructions[tex].[/tex]
