Final answer:
A topical organization pattern is most suitable for an informative presentation, where the main ideas are broken down into subcategories for clarity.
Step-by-step explanation:
Most of the time, a topical organization pattern will work best for an B. Informative presentation. This pattern breaks main ideas into smaller ideas or subcategories. For an informative speech, which aims to explain, describe, or demonstrate information comprehensibly to an audience, organizing content by subtopic is an effective method. Unlike persuasive speeches which may benefit from problem-and-solution or cause-and-effect patterns, an informative presentation focuses more on clarity and organization of information rather than persuasion. In such speeches, visual aids, three-dimensional objects, or videos are often incorporated to elucidate content.
