You can only date slide when:

• A. During finalizing documentation
• B. Duplicating
• C. Creating a new master patient
• D. Teleported patients only

Answer: (B)

Dating a slide happens when you duplicate it, because duplication creates a brand-new copy with its own timestamps. When you duplicate, the system makes a new item that gets new creation and modification dates, so the slide can be dated in this fresh context. Other actions like finalizing documentation, creating a new master patient, or dealing with teleported patients do not generate a new slide copy or reset its date fields, so they don’t establish a new dating moment for the slide. That’s why duplicating is the only action that yields a new date for the slide.
