Which of the following is not a category of the graphics standards ?

  • A.Basic graphics system
  • B.Portable network graphics
  • C.Open GL
  • D.Open Raster

Answer: A

The option that is not a category of graphics standards is Basic graphics system.

The other three are real, named standards or specifications. Portable Network Graphics (PNG) is a lossless raster image format, published as the W3C and ISO/IEC 15948 standard. OpenGL is the cross-language programming interface for rendering 2D and 3D graphics, maintained by the Khronos Group. OpenRaster is an open file format for layered raster images, used by painting programs such as Krita and MyPaint. 'Basic graphics system' is a generic phrase and does not name any standard.

What could not be confirmed: no reference was found that splits graphics standards into categories under these headings, so the key is kept and the answer rests on this elimination. A candidate who knows GKS and PHIGS as the classic graphics-system standards should not read 'Basic graphics system' as one of them.
