Task: Answer the multiple-choice question.
Question: Which drug has a 14.444\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1ccc(C2=NN(C(=O)c3cccs3)C(c3ccc(OC)cc3)C2)cc1
(b) COC(=O)C1C(=O)C(C(=O)c2ccc([N+](=O)[O-])cc2)C(=O)CC1(C)C
(c) COc1cc(C(=O)NCCOc2ccc(F)cc2)c(Br)c(OC)c1OC
(d) O=C(CNC(=O)c1ccc(Cl)cc1)OCC(=O)N1CCCC1
Answer: b. COC(=O)C1C(=O)C(C(=O)c2ccc([N+](=O)[O-])cc2)C(=O)CC1(C)C
