The correct answer is: A. relative organization
Relative organization is a file organization method in which each record is assigned a unique number, called a relative record number (RRN), which is used to locate the record on the storage device. The first record in the file has an RRN of 1, the second record has an RRN of 2, and so on.
Relative organization is a simple and efficient file organization method. It is easy to implement and understand. It is also efficient for both sequential and random access.
Key fielding is a file organization method in which each record is assigned a key field. The key field is a unique field that is used to identify the record. The key field is used to locate the record on the storage device.
Dynamic reallocation is a file organization method in which the file is dynamically reallocated as needed. This means that the file can grow or shrink as needed. Dynamic reallocation is useful for files that are constantly being updated.
Hashing is a file organization method in which each record is assigned a hash value. The hash value is a unique value that is used to locate the record on the storage device. Hashing is a very efficient file organization method for random access.
None of the above options are correct.
