Task: Answer the multiple-choice question.
Question: Which drug has a -73.751% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: NC(=O)CC(c1ccccc1)c1ccc2c(c1)OCO2
b: Cc1nnc(SCc2cc([N+](=O)[O-])cc3c2OCOC3)n(N)c1=O
c: CCC1Nc2ncnc(N3CCN(c4ccccn4)CC3)c2N(Cc2ccc(Cl)cc2)C1=O.O=C(O)C(F)(F)F
Answer: c. CCC1Nc2ncnc(N3CCN(c4ccccn4)CC3)c2N(Cc2ccc(Cl)cc2)C1=O.O=C(O)C(F)(F)F
