Final answer:
The correct thesis statement is Sentence 4 as it includes a clear subject, opinion, and reasons that make the statement debatable and specific.
Step-by-step explanation:
The correct thesis statement among the options provided is the fourth one. A thesis statement should clearly articulate the main argument of the essay and be specific, debatable, and clear, including a statement of fact, the writer's opinion, and the reasoning which supports the argument. Sentence 4 successfully meets these criteria by stating that "Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.", which provides the topic (peanut butter and jelly sandwiches), an opinion on the topic (they are the best), and reasons for that opinion (versatile, easy to make, and taste good).
