Which tool uses Option + Left Click to sample a source point?

• A. Brush
• B. Eraser
• C. Healing Brush
• D. Clone Stamp

Answer: (D)

Sampling a source point is how the Clone Stamp tool works. On a Mac, you set the point from which pixels will be copied by holding Option and clicking once to define the source, then you brush to paint those sampled pixels into the destination area. This direct use of a defined source point is the defining action of cloning pixels from one part of the image to another. The Healing Brush also involves sampling, but it uses that sample to blend and heal textures rather than copy exact pixels, so the question’s emphasis on sampling a source point for cloning points most clearly to the Clone Stamp.
