Task: Answer the multiple choice question.
Question: Which drug has a 0.109\% 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] O=C(NNC(=O)c1ccccc1[N+](=O)[O-])c1csc(N2CCOCC2)n1
[b] Oc1ccc(-c2[nH]nc(-c3ccccc3)c2-c2nc3ccccc3[nH]2)cc1
Answer: a. O=C(NNC(=O)c1ccccc1[N+](=O)[O-])c1csc(N2CCOCC2)n1
