Which of the following NoSQL databases is considered a document database?

EXPLANATION

A NoSQL (originally referring to "non SQL" or "non relational") database provides a mechanism for storing and retrieving data which is modeled in means other than the tabular relations used in relational databases. MongoDB is document-oriented database, or document store, designed for storing, retrieving, and managing semi-structured data.. Cassandra, Druid, and HBase are column databases, a NoSQL object of the lowest level in a keyspace. It is a tuple consisting of three elements: unique name, value, and timestamp.
