Who or what does the underlined pronoun refer to in the following sentence?
Yasir and Jamilah have the best grades in chemistry because both of their parents are science teachers.
A. parents
B. chemistry
C. Yasir and Jamilah
D. science teachers
Because it says 'both of their parents' and it was talking about Yasir and Jamilah before, I'm assuming that the their is the way the parents belong to the children.
