Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 8.941\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(COC(=O)c1cccc(S(=O)(=O)N2CCc3ccccc32)c1)Nc1ncc(Cl)cc1Cl
[b] COc1ccc(Br)cc1CNc1ccccc1.O=C(O)C(=O)O
[c] O=c1c(-c2ccc([N+](=O)[O-])cc2)coc2c(O)c(O)ccc12
[d] CCN(CC)c1cc(C)nc2ncnn12
Answer: c. O=c1c(-c2ccc([N+](=O)[O-])cc2)coc2c(O)c(O)ccc12
