Show answer & explanation
Correct answer: A
Answer: A simple reflex agent selects actions only on the basis of the current percept, completely ignoring the rest of the percept history.
Why this is correct: Simple reflex agents use condition–action rules (if percept then action). They do not maintain internal state or memory of past percepts.
Key property: Actions are determined solely by the current percept.
Advantage: Simple and fast because no memory or reasoning about history is required.
Limitation: Fails in partially observable environments where past percepts are needed to infer the state of the world; such tasks require agents with memory or a model of the environment.
Short example: If the current percept indicates "obstacle ahead", the agent immediately executes the action "turn right" based only on that percept.
