Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.901\% 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, b, or c without using any other words.
Options:

b: CCN(CC)C(=O)C(Oc1ccc(S(=O)(=O)N2CCCC2)cc1[N+](=O)[O-])c1ccccc1
c: O=C(Nc1ccc(Br)cc1)c1ccc2c(c1)OCO2
Answer: b. CCN(CC)C(=O)C(Oc1ccc(S(=O)(=O)N2CCCC2)cc1[N+](=O)[O-])c1ccccc1
