Can you specify the security group that you created for a VPC when you launch an instance in EC2-Classic?

Can you specify the security group that you created for a VPC when you launch an instance in EC2-Classic?
A . No, you can specify the security group created for EC2-Classic when you launch a VPC instance.
B . No
C . Yes
D . No, you can specify the security group created for EC2-Classic to a non-VPC based instance only.

Answer: B

Explanation:

If you’re using EC2-Classic, you must use security groups created specifically for EC2-Classic. When you launch an instance in EC2-Classic, you must specify a security group in the same region as the instance. You can’t specify a security group that you created for a VPC when you launch an instance in EC2-Classic.
