Task: Answer the multiple choice question.
Question: Which drug has a -16.712\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1cc(NNC(=O)Nc2cccc(Cl)c2)nc2c1c(C)nn2C
b: O=C(NCCN1CCOCC1)c1cc2cc([N+](=O)[O-])ccc2s1
c: CN(C)S(=O)(=O)c1cccc(NC(=O)CSc2nc3ccccc3[nH]2)c1
Answer: b. O=C(NCCN1CCOCC1)c1cc2cc([N+](=O)[O-])ccc2s1
