Task: Answer the multiple-choice question.
Query: Which drug exhibits a 16.427\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CN(CC(=O)OCC(N)=O)S(=O)(=O)c1ccc(Cl)cc1
b O=c1[nH]c(=S)n(-c2ccc(Br)cc2)c2ncccc12
Answer: a. CN(CC(=O)OCC(N)=O)S(=O)(=O)c1ccc(Cl)cc1
