Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.560\% 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) CCOc1ccc(N(C(=O)c2cc3ccccc3oc2=O)C2C=CS(=O)(=O)C2)cc1
b) NNC(=O)C1CC(O)CN1S(=O)(=O)c1ccc(Cl)cc1
c) CCOC(=O)c1cnn(-c2ccc(F)cc2)c1N
Answer: b. NNC(=O)C1CC(O)CN1S(=O)(=O)c1ccc(Cl)cc1
