Task: Answer the multiple choice question.
Question: Which compound has a 15.478% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(C(=O)NCc2nnc(SCC(=O)Nc3ccccc3OC)n2C)cc1
b: O=C(C/C=N\OCc1ccc([N+](=O)[O-])cc1)Nc1ccc(Br)cc1
c: Nc1c(-c2ccccc2)cnc2c(-c3ccccc3)cnn12
d: CN(C)c1ccc(/C=C/c2ccc3ccccc3[n+]2C)cc1.[I-]
Answer: b. O=C(C/C=N\OCc1ccc([N+](=O)[O-])cc1)Nc1ccc(Br)cc1
