Task: Answer the multiple choice question.
Query: Which drug has a 16.620\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=S(=O)(c1ccccc1)N1CCCC1c1nc2ccccc2s1
[b] COc1cc(/C=N/NC(=O)[C@H](Cc2c[nH]c3ccccc23)NC(=O)OCC(C)C)cc([N+](=O)[O-])c1O
[c] COC(=O)C1=NN(C(C)=O)C2(CC(=O)N(c3cccc(C)c3)C2=O)C1
[d] COCC(=O)Nc1ncc(S(=O)(=O)c2ccc([N+](=O)[O-])cc2)s1
[e] CCOC(=O)c1c(C)nc2c(c(SC)nn2-c2ccccc2)c1N
Answer: e. CCOC(=O)c1c(C)nc2c(c(SC)nn2-c2ccccc2)c1N
