What is the primary function of Artificial Intelligence (AI)?

The primary function of Artificial Intelligence (AI) is to enable machines to perform tasks that typically require human-like intelligence. This encompasses various capabilities such as understanding natural language, recognizing patterns, making decisions, and solving problems. AI systems can analyze large amounts of data quickly and effectively, mimicking cognitive functions that humans use in everyday tasks.

By automating these intelligent actions, AI can enhance efficiency and accuracy in various fields, including healthcare, where it can assist in diagnosing conditions, personalizing treatment plans, and improving patient outcomes. Thus, option A accurately captures the essence of AI's primary function, reflecting its role as a transformative technology that enhances decision-making and operational processes across different sectors.

Other options do not encompass the broader function of AI. For example, while data collection in healthcare is an important aspect, it does not represent the full scope of what AI is capable of achieving. Similarly, AI is not merely a type of hardware nor is it a regulatory framework, as these aspects do not encompass the intelligence-performing capability that AI embodies.
