Answer:
C. Students who did not complete high school.
Step-by-step explanation:
This public service ad is most likely intended for students who did not complete high school. In this ad, we see a woman graduating. She is hugging two young girls, which suggests that she might be their mother. Moreover, the ad tells us that she would have been unable to complete her degree without the support of her family. The ad most likely wants to encourage students who did not complete high school to do so, even if they are past the usual age.
