Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -26.601% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(NCc1cccnc1)c1ccc(NC(=O)c2cccc([N+](=O)[O-])c2)cc1
b: O=C1CN(S(=O)(=O)c2ccc(Cl)cc2)CC(=O)N1CCc1ccccc1
c: O=C(C(=C1N(Cc2ccc(Cl)nc2)CCN1Cc1ccc(Cl)nc1)[N+](=O)[O-])C(Cl)Cl
d: O=C(CS(=O)c1ccc(C(F)(F)F)cc1[N+](=O)[O-])Oc1ccccc1
e: Cc1nc(NCC2CCCO2)c2nnn(Cc3ccccc3Cl)c2n1
Answer: c. O=C(C(=C1N(Cc2ccc(Cl)nc2)CCN1Cc1ccc(Cl)nc1)[N+](=O)[O-])C(Cl)Cl
