EB for multiple app version RDS for automatic backups

The company also wants to reduce its operational overhead = A

A is correct since AWS Elastic Beanstalk support automatic scale with Load Balancer and autoscaling group and RDS Multi-AZ DB support MySQL and manage backups of the database in different AZs

It has to be the most efficient solution

With ElasticBeanStalk create you can create a web server, with EC2 instances, Load balancer, Auto Scaling, ... https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html and also you can add a MySQL: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.db.html

The MOST operationally efficient solution that meets these requirements would be option D: Create an Amazon Machine Image (AMI) that contains the application code. Create an Auto Scaling group that is based on the AMI. Integrate the Auto Scaling group with an Application Load Balancer for the web servers. Migrate the database to an Amazon RDS Multi-AZ DB instance. Option D provides a highly available and scalable solution with minimal operational overhead. By using an Amazon Machine Image (AMI) and an Auto Scaling group, the web servers can automatically scale in response to demand. The Application Load Balancer can distribute traffic evenly across the web servers, improving performance and reliability. Using Amazon RDS Multi-AZ DB instance provides high availability and automatic failover in case of a database outage. The RDS service also provides automated backups and maintenance, reducing operational overhead for the company. The use of RDS also allows for easy deployment of multiple versions of the application concurrently.

It should be A
