The Log Message option in the Breakpoint Settings allows the user to log custom information at each breakpoint while executing a process in Debug mode. This option can be accessed by right-clicking on a breakpoint and selecting Breakpoint Settings. The user can then enter a message that will be logged in the Output panel when the breakpoint is hit. The message can include variables, arguments, and pseudovariables, such as $PID, $TID, $FUNCTION, etc1

Option B is not recommended, because it requires the user to insert a Log Message activity before each activity with a breakpoint, which can be tedious and clutter the workflow. Option C is not relevant, because it enables or disables logging for all activities in the project, not just the breakpoints. Option D is not related, because it shows the execution flow of the process, not the custom information at each breakpoint.
