A

I used a venn diagram.

Left circle = Art @ 15%. right circle = Music at 10%

(1) tells us 2/3 of the students who are enrolled in an art class (10% of total Population) are also enrolled in a music class. This means that the all of students enrolled in music are also enrolled in an art class. Sufficient.

(2) Doesn't tell us anything about the relationship between the 2 classes. In sufficient.
