Security groups are associated with network interfaces. After you launch an instance, you can change the security groups associated with the instance, which changes the security groups associated with the primary network interface (eth0)

B is the right answer.
See http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html
After you launch an instance in a VPC, you can change its security groups. Security groups are associated with network interfaces. Changing an instance’s security groups changes the security groups associated with the primary network interface (eth0).
Note: After you launch an instance in EC2-Classic, you can’t change its security groups.

.Practically checked . create VPC and try to delete default sg of that VPC.
Below is the error :-
We could not delete the following security group (sg-4f55bd30)
the specified group: “sg-4f55bd30” name: “default” cannot be deleted by a user (Service: AmazonEC2; Status Code: 400; Error Code: CannotDelete; Request ID: bfc2dd66-9325-4ebb-b265-46a971eb8532)

Lol wut? Are you reading the questions? It doesn’t ask if you can delete default SG as it obviously is not possible. Each VPC must have at least 1 SG, ACL and route table.
B is the right answer, once VPC is launched you CAN modify the SGs. You can create new ones, edit inbout and outbound rules which takes effect immediately.
