Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.285\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a CC(c1nc2ccccc2s1)N(C)C(=O)c1ccccc1Br
b COc1ccc(CC2(C)OC(c3ccc(Cl)cc3)=NN2C(C)=O)cc1
c FC(F)(Cl)c1nnc2ccc(Sc3ccccn3)nn12
Answer: a. CC(c1nc2ccccc2s1)N(C)C(=O)c1ccccc1Br
