Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.421% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) COc1cccc(CN=c2c([N+](=O)[O-])nn(-c3ccccc3C)n2O)c1
(b) CC(CNS(=O)(=O)c1ccccc1)Sc1nncn1C
Answer: b. CC(CNS(=O)(=O)c1ccccc1)Sc1nncn1C
