Correct answer: C

Every 15-year-old is a teenager: 15-year-olds sits inside Teenagers.
18- and 19-year-olds are teenagers who can vote, and voters over 19 are not teenagers: Voters overlaps Teenagers.
No 15-year-old can vote: Voters does not meet the 15-year-olds circle.
So a small circle sits inside a larger one, with a third circle overlapping the larger circle only.

Worth noting

The third circle cuts the large circle but must miss the small one. The picture where it cuts both would make some 15-year-olds voters.
