D.They may have special meaning to the operating system.

Explanation:

There are many special characters apart from the alphabets and numbers on the keyboard. When it comes to programming and writing code, special characters  have already been assigned their functions.

They can be used as and when they are required. However, when it comes to naming files, it is a rule that file names are only allowed to contain letters and numbers.

This is because each and every special character have a predefined meaning to the operating system and command prompt. If special characters were allowed in the file name, it would create chaos and the operating system may end up in a state of ambiguity.
