The correct choice is C, since Redis Database is not a component of the Apache Kafka ecosystem. Kafka is primarily centered around messaging, streaming, and data storage solutions designed to handle large volumes of real-time data.

Kafka Connect is a tool for connecting Kafka with external systems, making it easier to import and export data. Kafka Streams is a powerful stream processing library that allows users to process data in real-time. Schema Registries are used in conjunction with Kafka to manage the schemas of the data being transmitted, ensuring compatibility and version control for data structures. These components work together to enhance Kafka’s functionality in data integration and processing.

On the other hand, Redis is an independent data structure store, commonly used as a database, cache, or message broker, but it does not integrate directly with the core functionalities that Kafka provides. Thus, it does not belong to the Kafka ecosystem.
