-
Software can borrow functionality.
-
They provide an IDE.
-
The debug software.
-
They write software automatically.
A
Correct answer
Explanation
Operating systems provide APIs and system calls that allow software developers to reuse common functionality, such as file handling or network communication, rather than writing it from scratch.
