Q1. Which of the following is a sound file format?
Explanation
WAV is a standard audio file format used to store sound data, commonly in uncompressed pulse-code modulation form. It is therefore the sound file format among the given choices. LOG files normally store event or activity records created by programmes or systems. DAT files are generic data files and are not specifically a sound format. DRV files are driver-related files used by operating systems or hardware components. Hence, the sound-file category matches WAV files, not the other listed file types.
