How do you disable anti-aliasing for a crisp selection when using the Polygon Lasso Tool or Magic Wand?

• A. Enable Anti-aliasing for crisper edges
• B. Use Edge Detection
• C. Set Feather Radius to 50
• D. In the tool options bar, uncheck Anti-aliasing to produce crisp, jagged edges

Answer: (D)

Anti-aliasing smooths the edges of a selection by blending edge pixels with their neighbors. To get a crisp, jagged edge with the Polygon Lasso Tool or Magic Wand, disable this smoothing. In Photoshop’s options bar for these tools, uncheck Anti-aliasing. This makes the edge align with the pixel grid, giving hard, pixel-perfect boundaries. The other options don’t achieve this: enabling anti-aliasing would smooth the edge; Edge Detection influences how the wand selects based on color changes; Feather Radius softens the edge rather than making it jagged.
