Task: Answer the multiple choice question.
Query: Which compound exhibits a -2.894\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CN1CCN(S(=O)(=O)c2cccc(S(=O)(=O)c3ccc(Cl)cc3)c2)CC1
b: CCn1nc(C)c(CNC(=O)C2CCC(=O)N(Cc3cccc(F)c3)C2)c1C
c: O=C(CNC(=O)c1ccccc1)N/N=C/C=C/c1ccccc1
Answer: a. CN1CCN(S(=O)(=O)c2cccc(S(=O)(=O)c3ccc(Cl)cc3)c2)CC1
