A Company Has an Amazon EC2 Instance Running on a Private

A company has an Amazon EC2 instance running on a private subnet that needs to access a public websites to download patches and updates. The company does not want external websites to see the EC2 instance IP address or initiate connection to it. How can a solution architect achieve this objective?

A) Create a site-to-site VPN connection between the private subnet and the network in which the public site is deployed.
B) Create a NAT gateway in a public subnet. Route outbound traffic from the private subnet through the NAI gateway.
C) Create a network ACL for the private subnet where the EC2 instance deployed only allows access from the IP address range of the public website.
D) Create a security group that only allows connections from the IP address range of the public website. Attach the security group to the EC2 instance.
