Which of the following is a representation of vector map? [a] Point, [b] Pixel, [c] Polygon

Correct option is D

Explanation of the Correct Option (d): [a] and [c] only
Why Point is a vector representation:
· Points represent discrete locations (e.g., wells, trees, weather stations).
· Defined by coordinates (x, y).
· Fundamental vector data type.
Why Polygon is a vector representation:
· Polygons represent area features (e.g., fields, lakes, administrative boundaries).
· Formed by closed lines connecting multiple coordinates.
· A core vector data structure.
Why Pixel is NOT a vector representation:
· Pixel is the smallest unit of raster data.
· Raster data represents space as a grid of cells.
· Hence, pixel does not belong to vector data.
Explanation of Other Options
Option (a): [a] only
· Incorrect because:
· Polygon is also a vector representation.
Option (b): [b] only
· Incorrect because:
· Pixel belongs to raster, not vector data.
Option (c): [a] and [b] only
· Incorrect because:
· Pixel is not a vector element.
Key Points Related to the Question
· Vector data types: Point, Line, Polygon
· Raster data unit: Pixel
· Vector data represents discrete features
· Raster data represents continuous surfaces
