Task: Answer the multiple-choice question.
Question: Which compound exhibits a -16.431% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCCCNC(=O)c1ccc2c(c1)N(CC)C(=O)c1ccccc1S2(=O)=O
b: CCCc1ccc(OCc2ccc(C(=O)N/N=C/c3cccc([N+](=O)[O-])c3)o2)c(OC)c1
c: CC(C)C[C@H](NC(=O)[C@@H]1Cc2ccccc2CN1)C(=O)Nc1ccc(C(C)C)cc1
d: O=C(Nc1ccc(S(=O)(=O)NCc2ccccc2)cc1)c1ccc(Br)o1
Answer: a. CCCCNC(=O)c1ccc2c(c1)N(CC)C(=O)c1ccccc1S2(=O)=O
