Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.137\% 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 additional words.
Options:
a O=C(NCc1cccnc1)c1ccc(Cl)cc1[N+](=O)[O-]
b CC1CCCN(C(=O)CSc2nnc(-c3cccnc3)n2C2CCCCC2)C1
c CN(CC(=O)Nc1ccc(Cl)c(Cl)c1)C1CCCCC1.O=C(O)C(=O)O
Answer: b. CC1CCCN(C(=O)CSc2nnc(-c3cccnc3)n2C2CCCCC2)C1
