The agent that deals with happy and unhappy states is the Utility-based agent.

Explanation:

1. Utility-based agent: This type of agent is designed to maximize its overall "happiness" or "utility" based on the states it encounters. It evaluates its current situation and makes decisions that lead to states that are more desirable or beneficial. In other words, it uses a utility function to measure the happiness associated with various states and chooses actions accordingly to move towards a more "happy" state.

2. Simple reflex agent: This agent operates on a set of predefined rules and responds directly to environmental inputs without taking into account any notion of utility or happiness.

3. Model-based agent: While it maintains an internal model of the world to deal with the current state, it doesn't specifically focus on happiness or emotional states; it's more about adapting to known environments.

4. Learning agent: This type of agent improves its performance over time based on past experiences but doesn’t specifically address the concepts of happiness or unhappiness in its operational model.

In summary, utility-based agents are the most directly involved with evaluating and making choices based on happy and unhappy states, using a formalized utility function to guide their actions.
