Task: Answer the multiple choice question.
Question: Which drug has a 16.475% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOc1ccccc1N(CC(=O)NCC1CCCO1)C(=O)CCC(=O)Nc1nccs1
b. Cc1ccc(NC(=O)COC(=O)CNC(=O)c2ccc3ccccc3c2)c([N+](=O)[O-])c1
c. O=C(Nc1ccc(Cl)cc1)Nc1csc([N+](=O)[O-])c1
d. O=C(O)Cc1ccc2oc(-c3ccccn3)nc2c1
Answer: c. O=C(Nc1ccc(Cl)cc1)Nc1csc([N+](=O)[O-])c1
