'Logos' is characterized as one of three 'modes of persuasion'(as stated by Aristotle, the other two being ethos, and pathos). It is primarily employed to persuade the audience logically or reasonably through factual and logical arguments. In the given situation, 'logos' is the rhetoric that Dr, Perez must employ since her subject seems quite factual i.e. 'causes and prevention of different skin diseases' and the audience educated and intellectual i.e. 'physicians'. Thus, the logical and rational claims would help appeal to the intellect and reason of the audience and convince them easily to believe in the claims. Therefore, <u>option A</u> is the correct answer.
