The expository prose is that in which the main purpose is to define or explain a concept, normally stating a thesis supported in topic sentences. A good example is that used to explain a scientific principle, or simply, the cause of a conflict or a war.
In this case, the paragraph does not convey any feeling from the author,so option A is not quite possible. It does not use any run-on sentences, which are those that are not linked properly or gramatically do not use the correct words to join the ideas the sentence expresses. It does not use filler words either,as it does not represent a dialogue or a conversation, and finally, although it focuses on a matter which might be important to students, this characteristic does not make this passage an exampleof expository prose, so, the correct answer to this question is B,because it expreses a clearly organized idea, which is that an application process can be difficult, sipprted by a sentence which aims to explain what the first step for a student should be.
