Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.971\% 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: CN(CC(=O)Nc1c(Cl)cccc1Cl)C(=O)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
b: O=C(CNS(=O)(=O)c1cccs1)NCc1ccc(F)cc1
Answer: b. O=C(CNS(=O)(=O)c1cccs1)NCc1ccc(F)cc1
