Problem statement: Answer the multiple-choice question.
Query: Which drug has a 8.558\% 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(NCCc1ccccn1)C1CC(=O)N(Cc2ccccc2Cl)C1
(b) O=S(=O)(Nc1ccc(Cc2ccncc2)cc1)c1ccc(Cl)s1
(c) CCS(=O)(=O)Nc1ccc(C2=NN(C(=O)c3ccccc3)C(c3cccs3)C2)cc1
Answer: b. O=S(=O)(Nc1ccc(Cc2ccncc2)cc1)c1ccc(Cl)s1
