Which of the following is a valid Layer type that constrains the visibility of a layer to the boundaries of another layer?

• A. Text Layer
• B. Layer Style
• C. Shape Layer
• D. Clipping Mask

Answer: (D)

Clipping masks confine a layer’s visibility to the shape defined by another layer below it. The bottom layer acts as the boundary or stencil, so the upper layer only shows through where the bottom layer has content (non‑transparent pixels). That makes the upper layer’s visible area exactly match the lower layer’s outline, which is why this is the right mechanism for constraining visibility.

The other options don’t perform this boundary-restriction role: a Text Layer is just text content, a Shape Layer holds vector shapes, and a Layer Style is only effects applied to a layer and doesn’t restrict visibility based on another layer’s content.
