Final answer:
Both the Clone Stamp and Healing Brush tools in image editing software require selecting a source area to remove elements from an image.
Step-by-step explanation:
The two tools that both require you to select a source area before removing elements from an image are the Clone Stamp tool and the Healing Brush tool. The Clone Stamp tool is used to copy pixels from one part of the image (the source area) to another. This can cover up the unwanted element by painting over it with pixels from the source area. The Healing Brush, on the other hand, operates similarly but also matches the texture, lighting, and shading of the sampled pixels to the area being healed for a more seamless repair.
