I got this question during an interview.

I want to ask this question from Generate Test Data in chapter MongoDB CRUD Concepts and Operation of MongoDB

Answer 1

Correct option is (b) insertData("test", "testData", 400)

The explanation is: If the collection and database do not exist, MongoDB creates them implicitly before inserting documents.
