Task: Answer the MCQ question.
Query: Which drug exhibits a -0.627% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC(C)(C)NC(=O)CSc1nc2ccccc2n1-c1ccccc1
b: COC1=C(Nc2ccccc2)C(=O)c2ccccc2C1=O
c: CCCCCN=CC1=C(O)CC(c2ccccc2)CC1=O
d: COc1cc(NC(=O)c2cncc(-c3ccc(C#N)cc3)c2)cc(C(=O)Nc2cccc(C(F)(F)F)c2)c1
Answer: b. COC1=C(Nc2ccccc2)C(=O)c2ccccc2C1=O
