Ethical Appeal.
This is because emotional appeal would be something that relates to your emotions like, "what if your mom was in a car accident? What if it was one of your family members? Thats why you should donate to this charity!" While ethical appeal relates to your ethics, like "If you saw a kid crying on the street alone, would you help this kid?" Of course, its only ethical! Bandwagon-ing is obviously not the choice because it is kind of like joining other people and following them and thats why you made that choice. Such as "Oh since everyone else is smoking, I should smoke too."(Don't smoke by the way, it's bad for you.) Sense of urgency is also obviously not because there is nothing urgent in this sentence at all.
