Show answer & explanation
Correct answer: B
Concept
A graphics standard defines output primitives as named operations for producing basic visual elements. Each primitive has a specific data model, such as a list of points for a line, markers, or a filled region.
In GKS, the standard output-primitives set includes POLYLINE, POLYMARKER, TEXT, FILL AREA, and CELL ARRAY. A label outside this standardized set is not a basic GKS primitive.
Application
Compare each offered name with the standardized GKS output-primitives set.
Contrast
POLYLINE represents connected line segments defined by a sequence of points.
POLYMARKER places marker symbols at specified points.
FILL AREA fills a region bounded by a sequence of points.
POLYDRAW is not one of the standardized GKS output-primitive names.
Cross-check
The official GKS overview lists the defined output primitives and does not list POLYDRAW, while the other three offered names correspond to listed primitives.
Result
Therefore, POLYDRAW is the offered term that is not a basic GKS primitive.
