Explanation:

The topic sentence is a summary of the main idea of a paragraph. Therefore, it compiles what the paragraph will deal with; while the rest of the sentences provide evidence, explanation, exemplification to support the concept of the topic sentence.

The other options are incorrect because a thesis statement can consist of one or two sentences, a controlling idea leads to a point that must be confirmed or developed, and a sentence fragment is an incomplete sentence.
