Which statement best describes the rules for a language?

• A. They are fixed and unchanging across time and place.
• B. They are productive meaning that users can produce an infinite number of new sentences.
• C. They are learned only through formal education.
• D. They apply only to spoken language, not written.

Answer: (B)

Language rules are productive: a finite set of grammatical patterns and vocabulary lets speakers generate an endless variety of sentences. With core structures for subject, verb, and object, plus ways to add tense, modifiers, and new words, people can create new, meaningful utterances never heard before. This generativity is why languages evolve, borrow terms, and keep expanding as communities communicate. That breadth is why the option describing productivity is the best fit. The other ideas miss key realities: languages aren’t fixed forever or the same everywhere, since they change with time and across communities; acquisition isn’t limited to formal schooling—children and new learners pick up rules through exposure and use in social settings; and language rules apply to both spoken and written forms, with writing simply enforcing and encoding those rules in a written system.
