Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 4.219\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COc1ccccc1N(C)S(=O)(=O)c1ccc(C(=O)NC(C)c2ccccc2)cc1
[b] CCc1ccc2c(c1)C(c1ccc([N+](=O)[O-])cc1)=NNC(c1ccccc1)=N2
Answer: b. CCc1ccc2c(c1)C(c1ccc([N+](=O)[O-])cc1)=NNC(c1ccccc1)=N2
