Microservices are primarily composed of loosely coupled self-contained services, which is essential for their functional design. This approach allows each service to operate independently, promoting flexibility and scalability within a system. In a microservices architecture, individual services are responsible for specific functionalities and can be deployed, updated, and scaled independently of one another.

This independence means that development teams can work on different services simultaneously without affecting the entire application, leading to faster deployments and easier maintenance. Additionally, since these services communicate over well-defined APIs, they can be developed using various programming languages and tools, allowing for technology diversity within the architecture.

The other options do not accurately represent the structure of microservices. Monolithic components suggest a single, tightly integrated application, which contrasts starkly with the fundamental principle of microservices. Similarly, interconnected databases imply a centralized data structure rather than the decentralized approach of microservices, where each service manages its own data. Lastly, single-point applications indicate a lack of modularity and independence that microservices strive to achieve.
