The physical location of a record is determined by a mathematical formula that transforms a file key into a record location in A. a tree file B. an indexed file C. a hashed file D. a sequential file E. None of the above

The correct answer is C. A hashed file.

A hashed file is a data structure that uses a hash function to map keys to file locations. The hash function is a mathematical formula that converts a key into a numeric value. The numeric value is then used to calculate the file location of the record.

A tree file is a data structure that uses a tree data structure to store data. The tree data structure is a hierarchical data structure that stores data in a way that allows for efficient lookups.

An indexed file is a data structure that uses an index to store data. The index is a data structure that stores the location of records in a file. The
