Problem statement: Answer the multiple choice question.
Query: Which drug has a 5.662\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CN(C(=O)CSc1nc2c(cnn2-c2ccccc2)c(=O)[nH]1)C1CCS(=O)(=O)C1
[b] CC(=O)c1c(C)[nH]c(C(=O)OCc2ccc([N+](=O)[O-])cc2)c1C
Answer: b. CC(=O)c1c(C)[nH]c(C(=O)OCc2ccc([N+](=O)[O-])cc2)c1C
