Task: Answer the multiple choice question.
Query: Which compound exhibits a -16.301% 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: COC(=O)c1ccc(N2C(=O)CC(SCCN)C2=O)cc1
b: CCOc1ccc(Cl)cc1S(=O)(=O)N1CCCC1
c: O=C(Nc1cccc2c1CCCC2)c1cc([N+](=O)[O-])cc([N+](=O)[O-])c1
d: COCCn1c(=O)[nH]c2cc(C(=O)Nc3cccc(C(C)=O)c3)ccc2c1=O
Answer: a. COC(=O)c1ccc(N2C(=O)CC(SCCN)C2=O)cc1
