Task: Answer the multiple choice question.
Question: Which compound has a 17.225\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a Cn1nc([N+](=O)[O-])nc1Sc1cccc2cccnc12
b O=C1N=c2ccc(Br)cc2=C1c1sc(=O)[nH]c1O
c O=C(O)c1ccc(CNS(=O)(=O)c2ccc(Oc3ccccc3Cl)cc2)cc1
Answer: b. O=C1N=c2ccc(Br)cc2=C1c1sc(=O)[nH]c1O
