Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.498\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1cccc(NC(=O)CN(C)C(=O)CCCc2nc3ccccc3s2)c1
b: O=C1N[C@@H](Cc2cn(S(=O)(=O)c3ccc([N+](=O)[O-])cc3)c3ccccc23)C(=O)N[C@H]1Cc1ccccc1
c: CCOC(=O)C(Cc1ccc(NC(=O)/C(=C\c2ccccc2)NC(=O)c2ccccc2)cc1)N1C(=O)c2ccccc2C1=O
d: COc1ccc(CCNC(=O)CNCC(c2ccccc2)N(C)C)cc1OC.O=C(O)C(=O)O
e: C=CCn1c(SCC(=O)NCCOC)nc2scc(-c3ccco3)c2c1=O
Answer: b. O=C1N[C@@H](Cc2cn(S(=O)(=O)c3ccc([N+](=O)[O-])cc3)c3ccccc23)C(=O)N[C@H]1Cc1ccccc1
