Problem statement: Answer the multiple choice question.
Query: Which compound has a -6.540\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) Cn1c(NCc2cccs2)nc2ccccc21
b.) CCN(CC(=O)Nc1ccc(NC(C)=O)cc1)C(=O)C12CC3CC(CC(Cl)(C3)C1)C2
c.) O=C(CN1C(=O)COc2ccccc21)NCCC1=CCCCC1
d.) O=C1CCN(C(=O)Cc2ccccc2[N+](=O)[O-])CC1
Answer: c. O=C(CN1C(=O)COc2ccccc21)NCCC1=CCCCC1
