Final answer:
The topic sentence mentioned introduces a classification type of informational text, where information is organized into categories (high clouds, mid clouds, and low clouds) with supporting details and evidence for each. Option b is the correct answer.
Step-by-step explanation:
The topic sentence 'There are three main categories of clouds: high clouds, mid clouds, and low clouds' would introduce a classification type of informational text.
Composition in English requires the understanding of various forms of writing, and in this case, classification involves organizing information into categories for the purpose of explaining the subject more clearly to the reader.
This is different from narrative, which would involve storytelling, persuasive, which would be aimed at convincing the reader, and descriptive, which would focus on detailed descriptions of a topic.
The structure of the paragraph following this topic sentence would likely adhere to the format of introducing each category of clouds and providing supporting details and evidence for each.
