Task: Answer the multiple-choice question.
Query: Which drug exhibits a 16.746\% 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. CCC(=O)OCCNc1cc(Sc2nc3ccccc3[nH]2)c2nonc2c1[N+](=O)[O-]
b. O=C(COC(=O)c1ccc2[nH]c3c(c2c1)CCCC3)Nc1ccccc1
c. CCOC(=O)Cn1cc(Cl)cc(C(=O)Nc2ccccc2)c1=O
d. CN(C)C=O.Cc1cc(-c2ccco2)c(C#N)c2nc3ccccc3n12
e. CN(Cc1ccccc1)C(=O)CN(c1ccccc1Cl)S(C)(=O)=O
Answer: b. O=C(COC(=O)c1ccc2[nH]c3c(c2c1)CCCC3)Nc1ccccc1
