Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.646\% 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. CCOC(=O)N/N=C1\CC(C)S(=O)(=O)c2ccc(Cl)cc21
b. CC(C)c1cc(C(=O)NC2CCCc3c2cnn3-c2ccccc2F)no1
c. CC(C)(C)C(=O)N(Cc1ccccc1)c1ccccn1
d. COC(=O)C1=C(c2cccc(C#N)c2)C[C@@H]2CC[C@H]1N2C(=O)N1CCOCC1
e. Cn1nc(-c2ccc(OCC(=O)Nc3ccccc3)cc2)c2ccccc2c1=O
Answer: e. Cn1nc(-c2ccc(OCC(=O)Nc3ccccc3)cc2)c2ccccc2c1=O
