Show answer & explanation
Correct answer: D
Concept
A file extension is the suffix after the final dot in a filename. It conventionally identifies the file format and the application or media family used to open or process the file.
Matching questions are solved by identifying each extension independently and then combining the four established pairs.
Application
.docx is the Office Open XML word-processing format used by Microsoft Word, so A pairs with III.
.jpg is a JPEG image format, so B pairs with I.
.mp3 is a compressed digital-audio format, so C pairs with IV.
.mov is a QuickTime movie container commonly used for video, so D pairs with II.
Cross-check
Grouping by media family gives one word-processing file, one image file, one audio file, and one video file; each List-II category is used exactly once.
Extension | Verified file family |
|---|---|
.docx | MS Word file |
.jpg | Image file |
.mp3 | Audio file |
.mov | Video file |
Contrast with the other sequences
A-III, B-I, C-II, D-IV assigns .mp3 to video and .mov to audio, reversing those two media families.
A-III, B-IV, C-I, D-II assigns .jpg to audio and .mp3 to image, reversing those two media families.
A-IV, B-I, C-III, D-II assigns .docx to audio and .mp3 to MS Word, reversing those two file families.
Result
Therefore, the complete matching is A-III, B-I, C-IV, D-II.
