Which activity should be used if the developer wants to conditionally execute another workflow?

The most suitable activity for conditionally executing another workflow is the "Invoke Workflow File" activity. This activity allows a developer to call another workflow file or process as part of the main workflow.

When using the "If activity," the developer can determine the condition for executing the workflow, but it does not inherently execute another workflow. Instead, it dictates the flow within the same workflow based on conditions. While the "Try Catch activity" is useful for error handling and managing exceptions, it does not focus specifically on conditional execution of workflows.

Involvement of the "Assign activity" is for assigning values to variables but does not provide any control flow to execute other workflows conditionally.

By using the "Invoke Workflow File" activity, the developer can create a modular and organized approach, ensuring that different workflows can be executed based on defined conditions, leading to cleaner and more maintainable RPA solutions.
