Assume an agent uses for its task the uniform cost search algorithm and no additional algorithms. Consider the following classification of intelligent agents: (1) simple reflex agent (2) goal-based agent (3) utility-based agent (4) learning agent

Then the agent is

Group of answer choices

only a learning agent

only a goal-based and learning agent

only a simple reflex agent

only a utility-based and learning agent

only a goal-based agent
