Task: Answer the multiple-choice question.
Query: Which compound has a 20.302% 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. COc1ccc(C2C(C#N)=C(N)Oc3n[nH]c(C)c32)cc1CSc1ccccn1
b. Cc1c(C(=O)NNS(=O)(=O)c2ccccc2Cl)sc(=S)n1C
c. O=C(Nc1ccc(Oc2ccc(NC(=O)Nc3ccc([N+](=O)[O-])cc3)cc2)cc1)Nc1ccc([N+](=O)[O-])cc1
d. O=C(CCS(=O)(=O)Cc1ccccc1)NC1CCCCC1
Answer: c. O=C(Nc1ccc(Oc2ccc(NC(=O)Nc3ccc([N+](=O)[O-])cc3)cc2)cc1)Nc1ccc([N+](=O)[O-])cc1
