Answer:
B. Sub point
Step-by-step explanation:
If you are looking for more in-depth information on one of the key points in a presentation, the most appropriate slide to provide that information would be the "Sub point" slide. The sub point slide is typically used to expand upon and provide additional details about a specific key point. It allows you to delve deeper into the topic and provide more comprehensive information to your audience. The "Key point" slide usually provides a concise summary or main idea, while the "Conclusion" slide summarizes the main points and wraps up the presentation. The "Work Cited" slide is typically used to list the sources or references used in the presentation.
