c. Descriptive grammar seeks to describe how language is actually used in the real world.
Explanation:
When we talk about descriptive grammar, we refer to a language's structure, its rules and the way these are implemented in everyday life by many speakers, including its many varieties, whether standard or nonstandard. On the other hand, prescriptive grammar makes reference to the use of language and its grammar rules, separating "good grammar" from "bad grammar", syntactically speaking.
