Task: Answer the multiple choice question.
Question: Which drug has a 16.019\% 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] CC(C)c1c(C(=O)N/N=C/c2cccs2)nnn1-c1nonc1N
[b] COc1ccc(CC(=O)NNS(=O)(=O)c2ccc([N+](=O)[O-])cc2)cc1OC
[c] O=S(=O)(c1ccccc1)c1nc(-c2ccco2)oc1Nc1ccccc1
[d] COc1ccc(/C=C2/C(=O)N(c3cccc(F)c3)N=C2C)c(OC)c1
[e] COc1cc(S(=O)(=O)NCc2ccccc2)ccc1F
Answer: b. COc1ccc(CC(=O)NNS(=O)(=O)c2ccc([N+](=O)[O-])cc2)cc1OC
