Which statement is true about programming languages?

• A. Programming languages require a compiler.
• B. Scripting languages require a compiler.
• C. All languages are interpreted.
• D. They cannot access external libraries.

Answer: (A)

The main idea here is how code gets turned into something a computer can run. A compiler is a program that translates high-level source code into machine code before execution, which is a traditional and widely used way to produce an executable. This makes the statement that programming languages require a compiler the best fit among the options because many languages rely on some translation step to run.

The other claims don’t hold as generally true. Scripting languages often run via interpreters or runtimes rather than needing a separate compiler in the traditional sense. Not all languages are interpreted—some are compiled, some are compiled to intermediate forms and then executed. And programming languages typically can access external libraries through linking or imports, not something inherent that would make the statement false.
