Answer options:

A.AWS RDS MySQL
B.AWS Aurora
C.AWS DynamoDB
D.AWS Redshift

Correct Answer - B
AWS Documentation mentions the following:
Amazon Aurora (Aurora) is a fully managed, MySQL and PostgreSQL compatible, relational database engine. It combines the speed and reliability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases. It delivers up to five times the throughput of MySQL and up to three times the throughput of PostgreSQL without requiring changes to most of your existing applications.
For more information on AWS Aurora, please refer to the URL below.
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Aurora.Overview.html
Note:
RDS is a generic service to provide Relational Database service which supports 6 database engines. They are Aurora, MySQL, MariaDB, PostgreSQL, Oracle, and Microsoft SQL Server. Amazon Aurora is a MySQL and PostgreSQL compatible enterprise-class database.
Please note that with AWS Aurora, you can get 5X the throughput of standard MySQL and 3X the throughput of standard PostgreSQL. Hence Option B is the correct answer.
