Why does changing only a file extension not change the actual file format?

Answer and explanation

Correct answer: The extension only indicates type while the internal data remains unchanged

A file format is governed by the internal structure and encoding of the file, including the way its data is organized. The extension is mainly a name-based hint that helps the operating system select an associated application. Renaming report.txt to report.jpg does not convert text data into an image; the contents remain unchanged. Therefore, option C is correct, while the other options confuse extension with size, location, or the operating system.
