Answer: The statement about revising the thesis statement that is true is A. It does not require revision; it states a limited subject and the writer's opinion of it.
Step-by-step explanation: The passage provided represents only the introduction of a larger piece of writing; however, the thesis statement ("Photography is a great hobby because it doesn't require expensive equipment, it can be done almost anywhere, and it provides lasting memories of people and places") presents in a clear way the subject that the author will be dealing with in the rest of the essay. Therefore, it states a limited subject: photography. Moreover, the writer also includes his/her opinion, which is made explicit by means of the adjective "great" and the presence of three reasons that have been introduced after the subordinating conjunction "because".
