What types of arguments can be used in a workflow?

In a workflow, various types of arguments are utilized to facilitate the flow of data and control between different components. The correct choice encompasses three distinct types: In, Out, and In/Out arguments, each serving a unique function.

In arguments are used to pass data into a workflow from an external source. This allows the workflow to receive necessary information to process and execute tasks. For instance, a workflow might need input parameters such as a filename or a specific value to operate effectively.

Out arguments serve the opposite purpose; they are meant to send data out of a workflow. This is crucial for returning results or processed data back to the calling context after the workflow has completed its execution. For example, a workflow that processes data might use an Out argument to deliver the results of that processing.

In/Out arguments combine both functionalities, permitting a workflow to both receive input and send output. This flexibility is particularly beneficial when the input data may need to be modified during the workflow's execution before being sent out. For instance, if a workflow takes an initial dataset, processes it, and then provides a modified version of that dataset, an In/Out argument allows for this seamless transition of data.

Using these three types of arguments together enhances the adaptability and reus
