Correct Answer: C. Amazon RDS for PostgreSQL

Explanation

Among AWS services, Amazon RDS for PostgreSQL is suitable for storing embedding vectors associated with real-time transactions. It delivers high performance, scalability, and high availability — characteristics well-suited for handling real-time transactional data. Other options — Amazon OpenSearch Service (optimized for search and analytics), Amazon Redshift (a data warehouse service), and Amazon DocumentDB (a MongoDB-compatible document database) — are not specifically designed for storing and processing real-time transaction-associated embedding vectors.
