1. MongoDB
2. NoSQL
3. Both A. and B.
4. None of the mentioned above

Answer: C) Both A. and B.

Explanation:

Indexes can be created in MongoDB to improve the performance of searches in the database. Any field in a MongoDB document can be indexed, including the document's name. When using MongoDB, indexes are used to speed up the execution of queries. Due to the lack of indexes, MongoDB is forced to perform a collection scan, which is to say it must scan each and every document in a collection, in order to select the documents that match the query statement. Whenever a query is associated with an appropriate index, MongoDB can use the index to reduce the number of documents that must be inspected by the query.
