The correct option is B Indexed file

A file that includes an index directory to facilitate random access is Indexed file

An indexed file is a computer file with an index that allows easy random access to any record given its file key. The key must be such that it uniquely identifies a record. If more than one index is present the other ones are called alternate indexes. The indexes are created with the file and maintained by the system.
