Task: Answer the multiple choice question.
Query: Which compound has a -9.432% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc([N+](=O)[O-])ccc1Cl
b) CCOC(=O)N1CCN(S(=O)(=O)c2ccc3[nH]cc(C(=O)O)c(=O)c3c2)CC1
c) COc1cc(/C=C2\SC(=Nc3ccccc3)N(CCc3c[nH]c4ccccc34)C2=O)ccc1OC(C)C(=O)O
d) COc1ccc(NC(=O)CSCC(=O)Nc2cc(Cl)ccc2N2CCCC2)cc1
Answer: a. CC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc([N+](=O)[O-])ccc1Cl
