Answer:
The sentence which possesses a tone that would be most appealing to a professor is:
d. Please allow me the opportunity to argue for a better grade.
Explanation:
A situation such as this, in which you need to address someone who is hierarchically superior to you and who has the power to change something that affects you, demands a certain type of tone and style. Since this refers to you addressing a professor, we can assume the use of formal language will be seen in more of a positive light. But that is not all. Politeness and diplomacy are also crucial. Take a look at option B, for instance. Even though the language is fine, it lacks diplomacy. It accuses the professor of having been sloppy, which will most likely offend him.
