Your organization was planning to develop a web application on AWS EC2. Application admin was tasked to perform AWS setup required to spin EC2 instance inside an existing private VPC. He/she has created a subnet and wants to ensure no other subnets in the VPC can communicate with your subnet except for the specific IP address. So he/she created a new route table and associated with the new subnet. When he/she was trying to delete the route with the target as local, there is no option to delete the route. What could have caused this behavior?
A. Policy attached to IAM user does not have access to remove routes.
B. A route with the target as local cannot be deleted.
C. You cannot add/delete routes when associated with the subnet. Remove associated, add/delete routes and associate again with the subnet.
D. There must be at least one route on the route table. Add a new route to enable delete option on existing routes.
