A thesis statement in a persuasive essay should be a clear sentence that gives the author's position on a topic as well as previewing the supporting reasons. In this thesis statement, the author takes the position that: "Computers should be used in all fourth-grade classrooms" and gives the reason: "to enhance students' technical ability." Option A is too "wishy washy". It says that there are "potential" benefits. Well, if you're going to write an essay to convince people to use computers in a classroom, it should be more guaranteed than that. Option B is good, but not great because it doesn't include how the computers can benefit. Option D is just bad. The scope of the topic is not big enough since the author has limited themselves to only talking about situations with only one teacher.

Computers should be used in all fourth-grade classrooms to enhance students' technical ability.
