Task: Answer the multiple-choice question.
Question: Which drug has a 17.688\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cn1c(=O)[nH]c(=O)c2c1nc(CN1CCN(c3cccc(Cl)c3)CC1)n2Cc1ccccc1Cl
b: COc1ccc(OC)c(N(CC(=O)NCc2ccncc2)S(C)(=O)=O)c1
c: Cn1c(NC(=O)c2ccc(F)c(F)c2)cc(=O)n(C)c1=O
d: CCOC(=O)C1CCCN(c2c(NCc3ccco3)c(=O)c2=O)C1
Answer: b. COc1ccc(OC)c(N(CC(=O)NCc2ccncc2)S(C)(=O)=O)c1
