What is the difference between 'Add Transaction Item’ activity and "Add Queue Item' activity?

According to the UiPath documentation1, the Add Transaction Item activity adds a new item in the queue and starts a transaction. The status of the item is set to InProgress. This means that the item is locked for processing by the current robot and cannot be retrieved by other robots until the transaction is completed or abandoned. The Add Transaction Item activity also returns the item as a QueueItem variable, which can be used to access its properties and data. The Add Queue Item activity adds a new item in an Orchestrator queue. The status of the item will be New. This means that the item is available for processing by any robot that uses the Get Transaction Item activity. The Add Queue Item activity does not return the item as a variable, but it allows setting its priority, reference, and deadline. Therefore, the correct answer is C. The status of the queue item added with ‘Add Transaction Item’ is “InProgress” The status of the queue item added with ‘Add Queue Item’ is "New’. References: 1: Queues and Transactions - UiPath Documentation Portal
