Which of the following is included in workflow properties?

Workflow properties in Smartsheet include critical metadata that help identify and manage workflows efficiently. The inclusion of Workflow ID and Created By in the workflow properties reflects essential details about the workflow itself. The Workflow ID serves as a unique identifier, which is crucial for tracking the workflow within the system, while the Created By attribute identifies the user who set up the workflow, providing accountability and context regarding its origin.

Other choices, while they might contain useful information, do not pertain directly to the core properties associated with workflows. The sheet name and last edited date relate to the sheet rather than the workflow itself. Total number of rows and columns focuses on the data structure rather than the workflow's operational characteristics, and the number of collaborators assigned is more about user permissions and roles than the fundamental properties of the workflow. Thus, Workflow ID and Created By are the correct elements that define what is specifically contained within workflow properties.
