Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.858% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCn1c(=O)cc(OCC(=O)NCCc2ccc(OC)c(OC)c2)c2ccccc21
[b] CC(=O)OCc1nc2sc3c(c2c(=O)[nH]1)CCCC3
[c] O=C(Nc1ccncc1)c1ccc(Cl)c([N+](=O)[O-])c1
[d] CCOC(=O)COc1ccccc1/C=C1\NC(=O)NC1=O
Answer: c. O=C(Nc1ccncc1)c1ccc(Cl)c([N+](=O)[O-])c1
