Task: Answer the multiple choice question.
Question: Which drug has a 1.024\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a Br.COc1ccc(-n2cc(-c3ccc(Cl)cc3)[nH]c2=S)cc1
b O=C(NNC(=O)c1ccc(-n2cncn2)c([N+](=O)[O-])c1)c1cccc(Cl)c1
Answer: b. O=C(NNC(=O)c1ccc(-n2cncn2)c([N+](=O)[O-])c1)c1cccc(Cl)c1
