What is usually present in the address bar if a site is not secure?

When a website is not secure, the browser typically indicates this through visible cues in the address bar. A common indicator is the presence of a symbol that signifies security status. If a site is deemed insecure, you will often see a red "X" through a padlock symbol, along with a red line through the "https" prefix. This serves as a clear warning to users that their connection to the website is not encrypted, meaning that data shared between the user's browser and the website could be intercepted or compromised.

In this context, the red "X" indicates that there is a significant security issue, while the red line signifies that the connection is not secure at all. Together, these indicators create a strong visual cue for users to avoid entering sensitive information, such as passwords or credit card details, on that site.

Other options may depict various forms of security indicators, like the red padlock or different color codes, but they do not reflect the specific scenario of a site being completely insecure as effectively as the combination described.
