Answer: The best example of a thesis statement for an essay that analyzes structure is B. Dr. King uses lists in his "I've Been to the Mountaintop" speech to explain his point.
Step-by-step explanation: The structure of a text or speech is related to the way in which the author/speaker organizes the information. For example, a writer can resort to graphics or diagrams and a speaker can use lists to present his ideas. In that way, the best example of a thesis statement for an essay that analyzes structure is B. ("Dr. King uses lists in his "I've Been to the Mountaintop" speech to explain his point") since it refers to the way in which the speaker organizes the information provided. In contrast, the other options refer to the literary devices he uses.
