If this paragraph stands by itself, sentence 1 is the topic sentence because it sets up sentences 2-5 to explain the many genres. If this paragraph is the introduction to an essay, or longer analysis into how a particular novel "engages the reader with profound insights into the human experience", then sentence 5 is the topic sentence and claim for the essay.
The best answer to the question that is being stated above would be the sentence that is numbered one (1): 'When it comes to fiction, there are many genres'. The next sentences are only subtopics and only support the main idea that are lots of genres for fiction.
