Final answer:
Option 'C' represents an informal writing style due to its conversational language and casual tone, which contrasts with the more formal tone of the other options.
Step-by-step explanation:
The question is asking which option represents an informal writing style. The answer is 'C. What is the deal with making everybody stay after school on Fridays to clean out the junk in the locker rooms?' This option uses conversational language and a casual tone, which are characteristic features of informal writing. In contrast, options A, B, and D are more formal in tone and structure, which would be more appropriate for formal communications such as letters or academic papers.
The academic English writing style has specific expectations, such as objectivity, clear structure, and the use of formal language without slang or colloquialisms. On the other hand, informal writing, like option C, can include slang, contractions, and a more relaxed tone, making it suitable for casual communications with friends or in certain online contexts.
An example of informal writing can be seen in personal emails or messages where a loose, casual style is acceptable. For instance, 'hi' as a subject line is informal, as opposed to a more formal approach that would include a detailed subject line and a business letter structure. The understanding of these different styles is crucial for effectively communicating within various contexts, whether that be in an academic setting, professional environment, or personal life.
