B. The instance is not configured with the proper key-pairs.
C. The Apache website cannot be accessed from the internet.

Correct Answer:A
In Amazon Web Services, when a user has configured an instance with Apache, the user needs to ensure that the ports in the security group are opened as configured in Apache config. E.g. If Apache is running on port 80, the user should open port 80 in the security group.
