Option C. language that is used in a particular region or by a particular group

C. language that is used in a particular region or by a particular group.

To arrive at this answer, let's look at each option:

A. language that follows strict rules for grammar, spelling, and punctuation: This option describes standard language usage, which is typically expected in formal writing and communication.

B. language that breaks from the rules of grammar, spelling, and punctuation: This option suggests non-standard language usage or even language errors, which could be considered a form of informal or colloquial speech.

C. language that is used in a particular region or by a particular group: This option accurately describes dialects. Dialects are variations of a language that reflect unique vocabulary, pronunciation, grammar, and other linguistic characteristics specific to a particular geographic region or social group.

D. language that is specific to a type of job or activity: This option describes jargon or specialized terminology used within a specific occupation or activity. While related to language variation, it does not capture the essence of dialects.

Thus, the correct answer is option C.
