Relating to computer networks, intranet, and the Internet, choose the correct option.


a) A characteristic of VPN (virtual private networks) is that they should never use encryption due to security and confidentiality requirements.
b) An intranet is an internal corporate network that allows the interconnection of company computers. Due to stricter security requirements, intranets cannot use WinZip to compress files and programs, making them take up less memory. It is common to use this program to reduce the size of files that are sent as attachments in email messages.
c) Files called cookies, also known as Trojan horses, are computer viruses with malicious intent that install themselves on the computer without the user's authorization and automatically and imperceptibly send information from the invaded computer.
d) Programs called worms are currently the most effective computer virus protection programs, protecting the computer against viruses, Trojan horses, and a wide range of software classified as malware.
