Explanation

Digital Audio Tape (DAT) was originally developed by Sony and Hewlett-Packard for high-fidelity audio recording. Because of its high storage density and sequential access capability, it was later adopted for computer data backup. The format uses a rotating drum mechanism similar to VHS, allowing gigabytes of data to be stored on a small cassette. Option B ('Digital Analog Tape') is not a real format - the name is self-contradictory. Both options A and C use the abbreviation DVT, which is not a standard backup tape format. Only DAT (option D) correctly identifies a real tape standard that bridged audio and data backup use cases.
