______ is a closed area of image bounded by straight or curved lines and filled with one solid colour.

  • A.Frame buffer
  • B.Polygon
  • C.Line
  • D.Point

Answer: B

A polygon is a closed area of the image bounded by straight or curved lines and filled with one solid colour. It is the basic filled shape in computer graphics.

A frame buffer is the memory that stores the image, a line is a single stroke, and a point is a single position, none of which is a filled closed area.

In computer graphics a polygon is a closed shape bounded by lines and can be filled with a single colour. Graphics systems store the picture in the frame buffer, and draw points, lines and polygons into it.
