Problem statement: Answer the multiple-choice question.
Question: Which drug has a -68.241% 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: Cc1ccc(Nc2nc(N)nc(CN3CCN(C)CC3)n2)cc1
b: Cc1ccccc1-n1c(C)cc(/C=C2\NC(=O)NC2=O)c1C
c: CC1CCc2c(sc(NC(=O)Cn3cnc([N+](=O)[O-])n3)c2C(N)=O)C1
d: COc1cc(CN2CCN(Cc3ccc([N+](=O)[O-])cc3)CC2)c([N+](=O)[O-])cc1OC.O=C(O)C(=O)O
Answer: d. COc1cc(CN2CCN(Cc3ccc([N+](=O)[O-])cc3)CC2)c([N+](=O)[O-])cc1OC.O=C(O)C(=O)O
