Which direction can arguments of a workflow have?

In UiPath workflows, arguments are used to pass data into and out of workflows, facilitating communication between different components. The possible directions for arguments in workflows are indeed "In," "Out," and "In/Out."

"In arguments" are used to pass data into the workflow, allowing the workflow to receive input information. "Out arguments" allow the workflow to send data back to the caller, effectively providing output to the calling context. "In/Out arguments" provide a way for the workflow to receive input data and also modify that data before sending it back to the caller.

Considering the functionalities provided by these argument types in a workflow, the answer suggesting that none of these directions exist is incorrect. In fact, a well-designed workflow can use any of the three types of arguments to handle data effectively throughout the automation process. Thus, there are indeed valid options for the directions arguments can take, contradicting the assertion made in the chosen answer.
