In UiPath, which option allows stepping through each activity line during debugging?

The ability to step through each activity line during debugging is essential for identifying and resolving issues within an automation workflow. The option that enables this functionality is "Step Into." When using "Step Into," the debugger executes the current line of code and then moves into any function or activity that is called on that line. This means that if the activity leads to a sub-sequence or a workflow, the debugger will follow through into that, allowing you to observe the execution at a more granular level.

In contrast, "Step Over" allows you to execute the current line but skips any sub-activities or functions, which means you don't see the details of those steps. "Run to this activity" skips all other lines until it reaches a specified activity, bypassing the opportunity to analyze the workflow's progression. Lastly, "Debug step" is not a standard term used in the UiPath debugging context, and may generally refer to the overall debugging process rather than a specific action. Therefore, "Step Into" is the correct choice for thoroughly investigating each activity line by line during a debugging session.
