Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -4.139\% 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: Cc1oc(-c2ccccc2Cl)nc1CS(=O)CC(=O)NCc1ccccc1Cl
b: COc1ccc(C)cc1-n1nnnc1SCC(=O)NNC(=O)c1ccc([N+](=O)[O-])cc1
c: O=C(Cc1ccccc1)Nc1ccc2c(c1)OC1(CCCC1)O2
Answer: b. COc1ccc(C)cc1-n1nnnc1SCC(=O)NNC(=O)c1ccc([N+](=O)[O-])cc1
