Respuesta :
The correct answer is C. Ethos
Explanation:
Ethos is a persuasive technique and appeal that focuses on using the experience, knowledge or reliability of the speaker as the main argument to convince the audience about an idea. This means if a speaker uses ethos he or she does not provide evidence to support the claim but information about himself/herself to convince the audience they should believe this speaker. This occurs in the case presented, because the speaker tells the audience about his experiences in international public service to convince them about donating overseas charities but the speaker does not provide evidence or reasons for doing this.
