Task: Answer the multiple choice question.
Question: Which drug has a 9.911\% 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) O=C(NNS(=O)(=O)c1ccccc1[N+](=O)[O-])c1cccc(Br)c1
b) CCC(=O)N(Cc1cc2ccccc2[nH]c1=O)c1ccc(OC)cc1
Answer: a. O=C(NNS(=O)(=O)c1ccccc1[N+](=O)[O-])c1cccc(Br)c1
