Which two artists are associated with Op Art?

• A. Seurat and Magritte
• B. Rene Magritte and Seurat
• C. Alfred Stieglitz and Howard Finster
• D. Bridget Riley and Victor Vasarely

Answer: (D)

Op Art is about creating visual effects that trick the eye through geometry, contrast, and repetition, so the image seems to move or vibrate as you look at it. The artists most closely tied to this movement are Bridget Riley and Victor Vasarely. Riley is renowned for her crisp black-and-white and color patterns—stripes, grids, and curves arranged with exacting precision—that produce strong optical sensations as the eye scans them. Vasarely is often called a founder of Op Art; his works use interlocking geometric shapes and bold color contrasts to build complex surfaces that appear to shift or pulse with viewing distance and angle. Together, they exemplify how Op Art relies on perception and viewer engagement rather than narrative content.

The other listed artists belong to different movements: Seurat is associated with Pointillism, Magritte with Surrealism, Stieglitz with photography and modernist movements, and Finster with outsider/folk art.
