Why are SSL and TLS important for online transactions?

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are essential protocols for encrypting data transmitted over the internet, which makes option B the correct choice. Their primary purpose is to ensure the safety and confidentiality of data during transmission, particularly in sensitive situations like online transactions. When you enter personal information, such as credit card details, SSL/TLS encrypts that data, making it unreadable to any potential eavesdroppers. This encryption helps protect against data breaches and maintains the trust of users who are submitting sensitive information online.

The other options do not accurately represent the main functions of SSL and TLS. While web page load times may benefit from various optimizations, SSL/TLS is not designed specifically for enhancing load performance. User access logs are typically a function of server-side applications, not directly related to SSL/TLS protocols. Finally, while secure transactions might facilitate smoother payment processes, the simplification of such processes is not a direct consequence of using SSL/TLS. The core significance of these protocols lies in their ability to secure data integrity and confidentiality during online communication.
