The protocol used for secure transmission of information when logging into a bank's website is HTTPS. This stands for HyperText Transfer Protocol Secure, and it is specifically designed to provide a secure connection over the internet. HTTPS encrypts the data transmitted between the user’s browser and the website, ensuring that sensitive information, such as login credentials and personal data, is protected from eavesdroppers and attackers.

When you visit a bank's website, HTTPS is essential because it not only provides encryption but also ensures that the data integrity is maintained, and that the user is communicating with the legitimate bank website rather than an impostor site. This is particularly crucial for online banking, where security and trust are paramount.

The other protocols listed are not suitable for this scenario. IMAPS is used for secure email retrieval, FTPS is for secure file transfers, and POP is for retrieving emails but does not provide a secure web transaction environment. Therefore, they would not be effective for securing a login session on a website, particularly in the context of banking where the protection of personal financial information is critical.
