Answer:
C. Layers
Step-by-step explanation:
Layers are the many levels where an image file can be placed in graphics tools. While making a digital image, layers can be mounted, blended, or specified in the tool. Layers are helpful since they allow you to add elements to an image and edit on them individually without permanently altering the primary image. You may change the hue and brilliance of each layer, add special features, relocate layer material, set transparency and blending settings, etc.
