Task: Answer the multiple-choice question.
Question: Which compound exhibits a 7.643\% 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 other words.
Options:
a: O=C(COC(=O)c1cccc([N+](=O)[O-])c1)NC1CCCC1
b: CCCOc1ccc(/C=C/C(=O)Nc2ccc([N+](=O)[O-])cc2C)cc1
c: CC(=O)c1ccc2c(c1)Cc1cc(C(C)=O)ccc1-2
Answer: b. CCCOc1ccc(/C=C/C(=O)Nc2ccc([N+](=O)[O-])cc2C)cc1
