RDS is cheaper than Aurora if you have a fixed instance size, but NOT if you have "unpredictable" usage patterns, then Aurora Serverless (!) is cheaper.

Since we have sporadic & unpredictable usage for DB, Aurora Serverless would be fit more cost-efficient for this case scenario than RDS MySQL. https://www.techtarget.com/searchcloudcomputing/answer/When-should-I-use-Amazon-RDS-vs-Aurora-Serverless

Answer C, MySQL-compatible Amazon Aurora Serverless, would be the best solution to meet the company's requirements. Aurora Serverless can be a cost-effective option for databases with sporadic or unpredictable usage patterns since it automatically scales up or down based on the current workload. Additionally, Aurora Serverless is compatible with MySQL, so it does not require any modifications to the application's database code.

Amazon RDS for MySQL is a cost-effective database platform that will not require database modifications. It makes it easier to set up, operate, and scale MySQL deployments in the cloud. With Amazon RDS, you can deploy scalable MySQL servers in minutes with cost-efficient and resizable hardware capacity². Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB is a good choice for applications that require low-latency data access¹. MySQL-compatible Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora (MySQL-compatible edition), where the database will automatically start up, shut down, and scale capacity up or down based on your application's needs³. So, Amazon RDS for MySQL is the best option for your requirements.

sorry i will change to C , because Amazon RDS for MySQL is a fully-managed relational database service that makes it easy to set up, operate, and scale MySQL deployments in the cloud. Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora (MySQL-compatible edition), where the database will automatically start up, shut down, and scale capacity up or down based on your application’s needs. It is a simple, cost-effective option for infrequent, intermittent, or unpredictable workloads.
