Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.283\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(/C=N/NC(=O)c2ccc(NC(=O)c3ccccc3Br)cc2)cc1
b: C=CCn1c(=O)c2c(nc3n2CCCN3Cc2ccccc2)n(C)c1=O
c: COc1ccc(C(=O)N/C(=C\c2cccc([N+](=O)[O-])c2)C(=O)Nc2cccc(C(=O)O)c2)cc1
Answer: b. C=CCn1c(=O)c2c(nc3n2CCCN3Cc2ccccc2)n(C)c1=O
