Task: Answer the multiple choice question.
Query: Which compound exhibits a 19.151% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(Cc2n[nH]c(=S)n2C)cc1Br
(b) CCOC(=O)c1cn(Cc2cccc(Cl)c2)nn1
(c) CCCn1c(C(C)Nc2nc(-c3ccc(Cl)c([N+](=O)[O-])c3)cs2)nc2cc(Cl)c(N3CCCCC3)cc21
Answer: c. CCCn1c(C(C)Nc2nc(-c3ccc(Cl)c([N+](=O)[O-])c3)cs2)nc2cc(Cl)c(N3CCCCC3)cc21
