Answer: Modify route tables for internet gateway traffic and adjust security groups for outbound traffic.
The correct answer is C. For EC2 instances in private subnets to receive internet traffic via an Application Load Balancer (ALB), their route tables need to be updated. Specifically, the route tables should direct traffic for 0.0.0.0/0 through the internet gateway. Additionally, the security groups for these EC2 instances must be modified to allow outbound traffic to 0.0.0.0/0. This configuration ensures that the EC2 instances can communicate with the internet through the ALB.
