Point out the correct statement.

(a) For $geoSphere queries that specify GeoJSON geometries with areas greater than a single hemisphere, the use of the default CRS results in queries for the complementary geometries

(b) When determining inclusion, MongoDB considers the border of a shape to be part of the shape, subject to the precision of floating point numbers

(c) The custom MongoDB CRS uses a anti-clockwise winding order

(d) None of the mentioned

This question was posed to me during an internship interview.

The question is from Index Types in section Index/Indexing Concepts of MongoDB

The correct answer is (b) When determining inclusion, MongoDB considers the border of a shape to be part of the shape, subject to the precision of floating point numbers

Easy explanation: The specified shape can be either a GeoJSON Polygon, a GeoJSON MultiPolygon, or a shape defined by legacy coordinate pairs.
