Task: Answer the multiple choice question.
Question: Which drug has a 23.009\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COc1ccccc1Nc1cc(C(=O)NCCCN2CCOCC2)c2ccccc2n1
b COc1ccc(C(=O)C2CCCN(Cc3nc4ccccc4nc3C)C2)cc1OC
c CC1(c2ccc3c(c2)OCCO3)NC(=O)N(CC(=O)Nc2ccccc2)C1=O
d O=C(COC(=O)CCN1C(=O)c2cccc([N+](=O)[O-])c2C1=O)NCc1ccccc1
e COc1ccc2nc(NC(=O)CSc3nccc(C)n3)sc2c1
Answer: d. O=C(COC(=O)CCN1C(=O)c2cccc([N+](=O)[O-])c2C1=O)NCc1ccccc1
