Final answer:
The correct answer is D, as slang often communicates your point effectively in informal settings, but is generally not appropriate for formal writing due to its casual nature and the expectation for standard English in professional contexts.
Step-by-step explanation:
Regarding the question, “Which of the following statements about slang is true?” the correct answer is D. Slang often communicates your point correctly, but it's not appropriate for formal writing. Slang can be a powerful and vivid tool for communication among specific groups because it reflects shared knowledge and culture. However, its informality and transient nature usually make it unsuitable for formal writing, where clarity and longevity of expression are critical. Careful consideration of your audience and the purpose of your writing is essential when deciding whether or not to use slang. While slang may be well-understood and effective in casual or personal communications, in academic and professional contexts, standard English is typically expected to maintain a level of formality and professionalism.
