Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.103\% 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. CCCNC(=O)N1CCC(C(=O)c2ccc(Cl)cc2)CC1
b. CC1CCN(c2ccccc2NC(=O)c2ccc([N+](=O)[O-])o2)CC1
c. C/C(N)=C(/C#N)C(=O)COC(=O)COc1ccc(Cl)cc1C
d. Cc1ccccc1N1C(=O)c2cccc3cccc(c23)C1=O
e. COc1cccc(N(C(=O)Cn2nnc(-c3ccc(C)o3)n2)C(C(=O)NC(C)(C)C)c2cccs2)c1
Answer: b. CC1CCN(c2ccccc2NC(=O)c2ccc([N+](=O)[O-])o2)CC1
