The opacity of a selected layer or group can be changed from 0% to 100%.

• A. The opacity can be changed from 0% to 100%.
• B. The opacity can be changed from 0% to 50%.
• C. The opacity can be changed only to 100%.
• D. The opacity cannot be changed

Answer: (A)

Opacity controls determine transparency for a layer or group. In Photoshop, you can set opacity anywhere from 0% to 100%. A value of 0% makes the layer completely transparent, while 100% makes it fully opaque. You can adjust this using the Opacity slider or by typing a value in the Layers panel. Since any percentage within that full range is valid, the statement is correct. It’s not limited to 50%, and the opacity can be changed, so options suggesting otherwise don’t fit.
