A company wants to build graph queries for real-time fraud pattern detection.

Amazon Neptuneis a fully managed graph database service optimized for storing and querying highly connected data. It supports popular graph models such as Property Graph and W3C's RDF, making it ideal for building graph queries for real-time fraud pattern detection and other applications that require complex relationships and data traversal.

B. Amazon DynamoDB: Incorrect, as it is a NoSQL database service that is not optimized for graph queries.

C. Amazon Timestream: Incorrect, as it is a time-series database service designed for storing and analyzing time-series data, not graph data.

D. Amazon Forecast: Incorrect, as it is a fully managed service that provides time-series forecasting capabilities, not for graph queries.
