C: Scalable index management and nearest neighbor search capability Explanation: The Amazon OpenSearch Service supports building vector database applications by enabling nearest neighbor search capability. This feature allows the service to efficiently perform similarity searches, which is crucial for applications that rely on vector embeddings (e.g., recommendation systems, image or text similarity searches). Combined with scalable index management, this makes OpenSearch an excellent choice for vector database applications.

Amazon OpenSearch Service provides scalable index management and supports nearest neighbor (k-NN) search, which is essential for building vector database applications. Vector databases store embeddings (numerical representations of data) and use k-NN search to retrieve similar data points based on proximity in the vector space, which is a foundational feature for applications such as recommendation systems, semantic search, and anomaly detection. These capabilities make OpenSearch ideal for developing vector-based applications.

c- The key feature of Amazon OpenSearch Service that enables companies to build vector database applications is its k-NN (k-nearest neighbors) functionality, specifically provided through the k-NN plugin. This allows OpenSearch Service to act as a vector database with efficient vector similarity search capabilities.
