Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 16.699\% 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] O=C(c1ccc(-c2cccc(C(F)(F)F)c2)o1)N1CCN(c2ccccc2O)CC1
[b] CCc1ccc2c(c1)C(c1ccc([N+](=O)[O-])cc1)=NNC(c1ccc(C)cc1)=N2
Answer: b. CCc1ccc2c(c1)C(c1ccc([N+](=O)[O-])cc1)=NNC(c1ccc(C)cc1)=N2
