Ageo_point
Bgeo_shape
Ckeyword
Dtext
Step-by-Step Solution

    geo_point only stores single points, and keyword or text are for strings, not shapes.

  3. Final Answer:

    geo_shape -> Option B

  4. Quick Check:

    Polygon data = geo_shape [OK]
Quick Trick: Use geo_shape for polygons, geo_point for single points [OK]
Common Mistakes:
MISTAKES
  • Using geo_point for polygons
  • Confusing keyword/text with geo types
  • Not recognizing shape complexity
