• B. Register is a fixed term used in all contexts.
• C. Register is the level of formality or style used in a context; language changes to suit different registers.
• D. Register is only about pronunciation.

Answer: (C)

Register is about the level of formality or style used in a given situation. This means language shifts to fit the context—who you’re talking to, why you’re talking, and where you are—affecting vocabulary, sentence structure, and even pronunciation. It’s not about how someone feels (sentiment), it isn’t a fixed term used in all contexts, and it isn’t only about pronunciation.

For example, you’d use a formal register in a job application or a courtroom, with precise terms, full sentences, and fewer slang features. You’d switch to an informal register with a friend, using contractions, slang, and simpler syntax. There are also specialized registers for different fields, like medical or legal language, which use their own vocabulary and conventions. The core idea is that language adapts to fit the social situation.
