Natural language processing is AI that...

• A. Understands human languages
• B. Analyzes images
• C. Understands programming languages only
• D. Creates artificial voices

Answer: (C)

Natural language processing focuses on teaching computers to work with human language—understanding, interpreting, and sometimes generating text or speech in everyday language. It supports tasks like translating, answering questions, and pulling meaning from written or spoken language. The best fit among the options is understanding human languages, because NLP is all about processing human language data, not images (which is computer vision), not programming languages (which relates to compilers/interpreters), and not creating artificial voices (which is speech synthesis).
