The correct answer is the cloud server, as it typically serves as the central hub for processing, analyzing, and storing large volumes of data collected from IoT devices. In the context of biometric data, the cloud server is equipped with advanced capabilities for data processing and can apply complex algorithms and machine learning techniques to analyze biometric information. This ensures that the data is properly processed, secured, and made ready for further review or action.

An IoT device, while it collects biometric data, often lacks the processing power necessary for handling large datasets or performing intricate analytics. The IoT gateway acts as a bridge between the IoT devices and the cloud or data management systems but is primarily responsible for data transmission rather than in-depth processing. The analytics server can analyze data, but it usually operates as part of a larger infrastructure that includes cloud servers and might leverage the cloud’s resources for comprehensive processing tasks.

In summary, the cloud server is designed to handle and process complex biometric data at scale, making it the appropriate answer.
