Task: Answer the multiple-choice question.
Question: Which drug has a -0.021\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccc(/C(C)=N/NC(=O)Cn2nc([N+](=O)[O-])cc2C)cc1
b: CC1C/C(=C/c2ccccn2)C(=O)/C(=C/c2ccccn2)C1
c: COc1ccc(-n2cnnc2SCC(=O)Nc2cc(S(=O)(=O)N3CCCCC3)ccc2C)cc1
d: O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCCSc1ccccc1
e: CCCC1(C(=O)OCC)NC(c2cc(OC)c(OC)c(OC)c2)C2C(=O)N(CC)C(=O)C21
Answer: b. CC1C/C(=C/c2ccccn2)C(=O)/C(=C/c2ccccn2)C1
