Which activity is used to pause execution for a specified time period?

The activity that is used to pause execution for a specified time period is the Delay activity. This activity allows developers to set a specific duration during which the automation will not proceed to the next step. By using the Delay activity, developers can control the timing of processes, which is particularly useful when waiting for external systems or conditions that require a pause before continuing.

In a robotic process automation (RPA) context, using delays can help to prevent issues such as trying to access a resource before it is available or synchronizing with user interfaces that may not be immediately ready for input.

The other options, while they may suggest a type of pause, do not specifically align with the standard terminology used in RPA development for this purpose.

In summary, the Delay activity is crucial for managing timing within automated workflows effectively.
