An adjustment layer can be used to adjust which of the following?

• A. Adjust Hue/Saturation, Levels, and Color Balance
• B. Adjust Exposure, Sharpen, and Noise Reduction
• C. Apply Photoshop Actions Only
• D. Change Image Size and Canvas Size

Answer: (A)

Adjustment layers provide non-destructive color and tonal edits that affect everything below them in the layer stack. They live as their own layers and let you tweak or remove the effect later, often with a mask to control where the adjustment applies.

Hue/Saturation, Levels, and Color Balance are classic examples of adjustments you can apply with an adjustment layer. They let you shift colors, contrast, and overall tone without permanently changing the original pixels, making it easy to dial in the exact look you want and revise later if needed.

Sharpen and Noise Reduction are typically done with filters or dedicated tools rather than adjustment layers, and changing image size or canvas size isn’t a tonal or color adjustment at all. Actions automate steps, not apply a specific color/tonal adjustment. So the combination listed aligns with what an adjustment layer is designed to do.
