Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 19.296\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1ccc(Br)cc1C(=O)N/N=C/c1ccc([N+](=O)[O-])cc1
b: CCN(CC)S(=O)(=O)c1ccc(NS(=O)(=O)c2ccc(F)cc2)cc1
Answer: b. CCN(CC)S(=O)(=O)c1ccc(NS(=O)(=O)c2ccc(F)cc2)cc1
