What happens when a breakpoint is hit during debugging?

When a breakpoint is hit during debugging, the application stops executing. This allows the developer to pause the application's flow at a specific point in the code. The purpose of a breakpoint is to enable thorough inspection of the current state of variables, evaluate how code behaves at that moment, and diagnose any issues. By halting execution, the developer can step through the code line by line, observe changes in variables, and better understand how the application's logic is working.

The other options do not accurately describe what occurs when a breakpoint is reached. For instance, the user session remains active, and the application does not automatically generate logs or save data during a breakpoint pause. The key function of a breakpoint is to facilitate real-time debugging, rather than performing any automatic functions related to session management or logging.
