Correct option is A

Rule-oriented grammar refers to a structured system of grammar that focuses on the explicit teaching and application of grammatical rules. This approach is characteristic of formal grammar, which is concerned with the correct structure and usage of language according to established norms. Formal grammar provides a framework for understanding the syntax and morphology of a language, emphasizing the rules that govern sentence formation and word usage.
Formal grammar is often contrasted with functional grammar, which focuses more on how language is used in context to convey meaning. While functional grammar emphasizes communicative purposes, formal grammar is more concerned with linguistic accuracy and rule adherence.
