Task: Answer the multiple choice question.
Question: Which compound has a 8.748\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=C(O)c1ccc([N+](=O)[O-])c(CS(=O)(=O)c2ccccc2)c1
b.) O=C(NNC(=O)C1CCCO1)c1ccc(Br)cc1
c.) CC(NC(=O)C(NS(=O)(=O)c1cccc2nsnc12)C(C)C)c1ccccc1
d.) O=S(=O)(c1cccc2nonc12)N1CCN(c2cccc(Cl)c2)CC1
Answer: b. O=C(NNC(=O)C1CCCO1)c1ccc(Br)cc1
