Step 1: Understanding website security protocols.
When users browse websites on the internet, data such as login credentials, payment details, and personal information may be transmitted between the user's browser and the web server. To protect this sensitive information from hackers or attackers, secure communication protocols are used.
Step 2: Role of SSL (Secure Socket Layer).
SSL (Secure Socket Layer) is a security technology that encrypts the communication between a web browser and a web server. Encryption ensures that even if data is intercepted, it cannot be easily read or misused.
Websites that use SSL display a secure protocol in their web address. Instead of starting with http://, they begin with https://. The extra "s" stands for secure.
Step 3: Analysis of the options.
(A) http:// Incorrect. This protocol does not provide encrypted communication.
(B) ssl:// Incorrect. This is not a valid URL protocol used by websites.
(C) https:// Correct. This indicates that the website uses SSL or TLS encryption to secure communication.
(D) ssls:// Incorrect. This is not a valid protocol.
Step 4: Conclusion.
Therefore, the web address starting with https:// indicates that the website is secured using SSL encryption.
Final Answer: https://
