Answer:
Try C, 4/15
Explanation:
The fraction for the entire model would be 4/30 and simplified would be 2/15 but the answer isn't there but theres a line in between the model so may be just asking for the bottom part since only the bottom part had blue. But tbh Im not exacly sure but 4/15 is the answer if the question only talking about the bottom part. Im really sorry it its wrong.
