Hello. You have not submitted the arguments to which this question refers, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
A persuasive argument is one that has the capacity to convince the reader about something. The author of this argument wants the reader to agree with what he is presenting and for this reason uses several evidences and supporting information to show that the argument is valid, true and that it must be adopted by the reader. Therefore, to answer this question, you must first read the arguments and see which one has less evidence, failing to show that it is correct and that it must be believed. In this case, this argument is the least persuasive.
