How should a solutions architect configure the communication between the EC2 instances and the DB instance?

• A.Configure the "web servers" security group to allow access to the "database" security group Configure the "database" security group to allow access from the Auto Scaling group
• B.Configure the "web-servers" security group to allow access to the "database" security group Configure the "database" security group to allow access from the "web-servers" security group
• C.Configure the "web-servers" security group to allow access to the DB instance's current IP addresses Configure the "database" security group to allow access from the Auto Scaling group
• D.Configure the "web-servers* security group (o allow access lo the OB instance's current IP addresses Configure the "database" security group to allow access from the current set of IP addresses in use by the EC instances
