Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.916\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CC(=O)CC1(OC(C)=O)C(=O)N(C)c2ccccc21
(b) O=C(Nc1ccc(F)c(F)c1)C1CCCN1S(=O)(=O)c1ccc(F)cc1
(c) CC(=O)NC1C(OCc2ccccc2)OC(CO)C(OC(C)=O)C1OC(C)=O
Answer: b. O=C(Nc1ccc(F)c(F)c1)C1CCCN1S(=O)(=O)c1ccc(F)cc1
