Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.138\% 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 additional words.
Options:
a. Br.CC1CCCC(C)N1Cc1cn2ccccc2n1
b. COc1ccc(CC(=O)Nc2cccc(-c3csc(C)n3)c2)cc1
c. CN(C)c1ccc(C(CNC(=O)c2ccco2)N2CCCC2)cc1
d. O=C(CCSCc1ccccc1Cl)NC1CCCC1
e. O=C(OCC(=O)N1CCCC1=O)c1cccc([N+](=O)[O-])c1
Answer: e. O=C(OCC(=O)N1CCCC1=O)c1cccc([N+](=O)[O-])c1
