Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.319\% 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: O=C(Nc1nc2cc3c(cc2s1)OCCO3)c1ccc([N+](=O)[O-])o1
b: CC(OC(=O)c1ccc(Cl)c(S(=O)(=O)Nc2ccc(F)cc2)c1)C(=O)NC(N)=O
c: CCCC(=O)c1ccc(N2CCN(C(=O)c3cccs3)CC2)c(F)c1
Answer: a. O=C(Nc1nc2cc3c(cc2s1)OCCO3)c1ccc([N+](=O)[O-])o1
