CorrectNot quiteAnswer A
Correct answer: A
Explanation
Some teachers are parents and some are not, so Teachers and Parents overlap.
Some teachers are graduates and some parents are graduates, and neither class is wholly inside Graduates: each pair overlaps.
Some people are all three (a teacher who is a parent and a graduate).
So the picture is three circles, each overlapping the other two.
Worth noting
Two circles inside a larger one would need every teacher to be a graduate, which the classes do not guarantee.
