True or False: A flow can be displayed when a site is in Preview mode.

The statement that a flow can be displayed when a site is in Preview mode is false. When a site is in Preview mode, the intention is to review how the site will appear to end users without it being live. Flows are designed to be user-interactive components that often require the site to be published for them to function properly and be displayed as intended. Therefore, flows are not accessible or viewable during the Preview mode, as this mode restricts user interactions to ensure that modifications can be made freely without affecting the live environment.

Understanding this distinction is crucial as it reflects the operational parameters that govern how Salesforce components function in various modes, which is especially relevant in scenarios involving user testing and website deployment.
