Question

Point out the wrong statement.

(a) If $near or $nearSphere query specifies the center point as a GeoJSON point, specify the distance as a non-negative number in meters

(b) If $nearSphere query specifies the center point as legacy coordinate pair, specify the distance as a non-negative number in radians

(c) $near can only use the 2dsphere index if the query specifies the center point as a GeoJSON point

(d) None of the mentioned

I had been asked this question in a national level competition.

The query is from Geospatial Index topic in section Index/Indexing Concepts of MongoDB

Answer 1

Correct choice is (d) None of the mentioned

To explain: $minDistance filters the results of a geospatial $near or $nearSphere query to those documents that are at least the specified distance from the center point.
