Task: Answer the multiple-choice question.
Query: Which compound exhibits a 14.222\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a Cc1cc(Oc2ccc(=O)n(C)n2)nc(Oc2ccc(=O)n(C)n2)n1
b NC(=O)c1ccc(NC(=O)CSc2nnc(-c3cccnc3)n2Cc2ccco2)cc1
c O=C(Nc1cccc(NC(=O)c2ccc([N+](=O)[O-])o2)c1)c1ccco1
Answer: c. O=C(Nc1cccc(NC(=O)c2ccc([N+](=O)[O-])o2)c1)c1ccco1
