Step Into is a debugging operation in UiPath Studio that allows developers to inspect workflow execution at the individual activity level.

Option B is correct because Step Into executes activities sequentially and allows the debugger to enter invoked workflows for detailed inspection.

When the debugger encounters an activity, Step Into highlights it before execution. This enables developers to examine execution behavior, inspect variable values, and identify the precise location of logic or data-related failures.

When the activity is an Invoke Workflow File, Step Into opens the referenced workflow in a separate read-only tab and permits the developer to execute its internal activities individually.

This behavior is especially valuable when diagnosing failures involving reusable components, nested workflows, data transformations, or verification activities in automated test cases.

Step Into differs from Step Over, which advances execution without opening the internal activities of the current invoked workflow or container. Step Out continues execution until the current container or invoked workflow is exited.

In UiPath Studio, the standard keyboard shortcut for Step Into is F11.

Option A incorrectly describes uninterrupted execution. Option C is incorrect because debugging does not automatically resolve exceptions. Option D describes behavior more closely associated with Step Over.

Step Into therefore provides granular execution control for diagnosing workflow behavior and verifying internal activity logic.
