Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.843\% 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. CCOc1ccccc1N(C)C(=O)c1ccc2c(=O)n3c(nc2c1)CCCCC3
b. Cl.OC(COCCOc1ccc(Br)cc1)CN1CCCCC1
c. O=C1C(=Nc2ccc(OC(=O)c3ccccc3[N+](=O)[O-])cc2)C(n2nnc3ccccc32)=C(O)c2ccccc21
Answer: c. O=C1C(=Nc2ccc(OC(=O)c3ccccc3[N+](=O)[O-])cc2)C(n2nnc3ccccc32)=C(O)c2ccccc21
