Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.802\% 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) O=C1CCCc2c1nc(-c1ccccc1F)n2O
b) CS(=O)(=O)N(CC(=O)Nc1ccccc1C(=O)N1CCOCC1)c1cccc([N+](=O)[O-])c1
c) COc1cc(C(=O)OC2CCN(C)CC2)cc(OC)c1OC.Cl
Answer: a. O=C1CCCc2c1nc(-c1ccccc1F)n2O
