Explanation:

The topic sentence of a body paragraph in an essay about fossil fuels should relate to the main idea of the paragraph (likely about problems with fossil fuels). The first option addresses the environmental pollution caused by fossil fuels, which fits as a topic sentence for a body paragraph on fossil fuel issues. The second option is about fish, irrelevant to fossil fuels. The third is a question about dinosaurs, also irrelevant.

Answer:

First option: Firstly, using fossil fuels is a problem because they pollute the environment.
