What is the purpose of a Smart Object in Photoshop?

• A. It stores a copy of the image on disk for faster editing.
• B. It converts pixels into editable vector paths.
• C. It preserves a layer's source data and enables non-destructive scaling, rotation, filters, and transformations.
• D. It merges the layer with the background, making edits permanent.

Answer: (C)

Smart Objects preserve the original layer data so edits happen non-destructively. This means you can scale, rotate, apply filters, or transform the object and still revert to or adjust the original content without permanently changing pixels. When you resize a Smart Object, Photoshop uses the stored source data to maintain quality, and you can apply Smart Filters that remain editable or removable later. You can open the Smart Object to edit its contents in its own document, and any changes update across all instances. You can also replace the contained data or link to an external file, keeping edits flexible and reversible. In short, the purpose is to protect the source data while enabling non-destructive transformations and effects. It’s not simply a cached copy for speed, not converting pixels into editable vectors, and not merging the layer with the background.
