Step 1: Understanding the term "Collage"
The word "collage" comes from the French word "coller" which means "to glue."
In art, collage refers to a technique in which different materials such as pieces of paper, newspaper, fabric, or other items are arranged and stuck down onto a backing surface to create a new visual composition.
Step 2: The origin of collage as a painting technique
Collage was first used as a formal technique in the early 20th century by modernist artists like Pablo Picasso and Georges Braque.
They used cut pieces of paper, newspapers, and cloth glued onto their canvases to express new forms and textures in their paintings.
Hence, collage painting is not done by traditional brushwork or on materials like glass or stone, but by assembling pieces of paper or similar material.
Step 3: Role of "cutting paper"
The main medium used in collage painting is paper—specifically, cutting different pieces of paper and arranging them creatively.
These paper pieces can include magazine clippings, patterned prints, text fragments, drawings, or any flat printable visual material.
The artist cuts and assembles these onto a canvas or cardboard and adheres them with glue or paste to form a new artwork.
Step 4: Analyzing the options
- Option (A) is correct because collage painting is indeed made by cutting and gluing pieces of paper.
- Option (B) "Glass" refers to glass painting or stained glass, not collage.
- Option (C) "Stone" is irrelevant here, as stone is not a medium for collage but for sculpture or carving.
- Option (D) "None of these" is incorrect since option (A) is clearly valid.
Step 5: Conclusion
Since collage painting is best described by the technique of cutting pieces of paper and pasting them to form an image, the correct answer is:
\[
