What layer option allows you to add content layers for inclusion and comparison?

• A. Add layer from page
• B. Link layer
• C. Merge layers
• D. Copy layer

Answer: (A)

When you want to include content as a separate, inspectable layer for comparison, you create a new layer from the page. This option takes the content from a page and places it onto its own layer, so you can turn that layer on or off, adjust its transparency, or compare it directly with other layers without changing the original page content. That separation is what makes side-by-side or overlay comparisons clear and non-destructive.

The other options serve different tasks: linking a layer ties to existing content rather than creating a new layer; merging layers combines them into one, losing the separate identities needed for comparison; copying a layer duplicates an existing layer instead of bringing in new content for inclusion and comparison.
