Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.998\% 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=C(Nn1cnnc1)c1cc(-c2ccccn2)nc2ccccc12
b O=C(NCCS(=O)(=O)N1CCN(c2ccc(F)cc2)CC1)C12CC3CC(CC(C3)C1)C2
c COc1ccc(N(C(=O)C(C)C)S(=O)(=O)c2ccc(Cl)cc2)cc1
Answer: b. O=C(NCCS(=O)(=O)N1CCN(c2ccc(F)cc2)CC1)C12CC3CC(CC(C3)C1)C2
