Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.310\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(O)CCc1ccc(-c2ccc(F)cc2)n1Cc1ccco1
b) O=C(c1cccs1)N1C(=O)c2cccc3cccc1c23
c) O=C(Oc1ccc(Cl)cc1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
Answer: c. O=C(Oc1ccc(Cl)cc1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
