Which concept refers to stacking elements on separate layers to allow non-destructive editing?

• A. Template
• B. Layers (Photoshop)
• C. Master pages (InDesign)
• D. Time-based design

Answer: (B)

Layering elements on separate layers allows non-destructive editing because each piece of the composition can be adjusted independently without changing the others. In Photoshop, placing objects, effects, and adjustments on their own layers means you can move, hide, transform, or apply masks and adjustments to just that layer. If a change doesn’t look right, you can tweak or remove it without ever altering the underlying pixels of other layers, and you can experiment freely, knowing you can revert to the original at any time. This separation is what keeps edits flexible and reversible.

Templates provide reusable layouts, master pages in InDesign create consistent page structures, and time-based design deals with changes over time or animation. None of these inherently describe keeping edits non-destructive by stacking elements on separate layers.
