Answer:
b. Doing what is right.
Step-by-step explanation:
I'm sure that if you've gone to a school concert or a poetry slam or something related to those, therefore you've heard of the word ethic. In this sense Ethic is to make sure you are doing what is right, for example guidelines you need to follow. If you are at a concert, at the beginning of it, someone might say what they expect of you. For example, please don't use the flash on your camera because it is distracting, is an example of using ethics because you know that you shouldn't do it. Another more common example, would be at the movie theatres, you need to turn of your phone. When you are watching a movie you are more intrested in what is happening there than on your phone, And even if you don't care about the movie, people around you might, and Its important that you follow those basic rules because you are doing what is right.
