An autonomous agent is characterized primarily by its ability to operate independently in its environment and adapt to changes that may occur. This defining feature means that the agent can perform tasks without needing continuous human input or oversight, allowing it to respond dynamically to new information or shifting conditions in its environment.

The capacity for adaptation is essential in many real-world applications of autonomous agents, such as in robotics, self-driving cars, and smart systems, where the environment can be unpredictable. An agent that can learn from experiences and adjust its actions is more effective in achieving its objectives, making it a true autonomous entity.

The other choices highlight attributes that do not align with the core concept of autonomy. For instance, requiring constant human supervision indicates a lack of independence, and functioning only in stable environments implies an inability to adapt. Additionally, the notion of predicting all future events accurately is not possible due to the inherent uncertainties present in many environments, which autonomous agents must navigate.
