Which feature preserves an image's source content with all its original characteristics (non-destructive editing)?

• A. Adjustment Layers
• B. Layer Comps
• C. Linked Files
• D. Smart Objects

Answer: (D)

Smart Objects keep the original image data inside a container, so the source content stays intact while you work. When you convert a layer to a Smart Object, Photoshop stores the actual pixels (and any vector data) separately. Transformations, filters, and other edits are applied non-destructively because they’re saved as instructions on the Smart Object rather than rewriting the original pixels. You can open the Smart Object to edit its contents, and those changes automatically update in the main document without losing the original data. This combination of preserving the original source and allowing flexible, non-destructive edits is why Smart Objects are the best fit.

Adjustment layers are also non-destructive, but they modify appearance rather than preserving the full original image data inside a single container. Layer comps capture different states of visibility and effects, not the source content itself. Linked files refer to external content and rely on the external file, rather than encapsulating the original image data within the document.
