A. B. C. D.D.
The correct answer is D. 443.
Explanation: The HTTP protocol is used to transmit data over the internet. However, this protocol does not provide any encryption or security for data transmission. To secure data transmission between the web server and clients, the Hypertext Transfer Protocol Secure (HTTPS) protocol is used. HTTPS is a secure version of HTTP that uses encryption to protect data transmission.
HTTPS is designed to use a secure communication channel over the internet. It uses Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols to encrypt data transmission. HTTPS is commonly used for secure transactions, such as online banking, shopping, and login pages.
The default port number for HTTPS protocol is 443. This means that if the system administrator wants to enable authentication on a web server's login page and encrypt authenticated sessions over HTTP protocol for all static HTML pages, they should use port 443 for secure communication.
In summary, option D (443) is the correct answer because it is the default port number for HTTPS protocol, which provides encryption and security for data transmission over the internet.
