Selected Answer: B
B. Network access control lists (network ACLs) "Security groups are tied to an instance whereas Network ACLs are tied to the subnet. Network ACLs are applicable at the subnet level, so any instance in the subnet with an associated NACL will follow the rules of NACL. That’s not the case with security groups, security groups have to be assigned explicitly to the instance." https://medium.com/awesome-cloud/aws-difference-between-security-groups-and-network-acls-adc632ea29ae
