Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.496% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1cc(C(C[N+](=O)[O-])c2c(C)cc3ccccn23)ccc1O
b: Cc1ccc(Nc2ncc(C(=O)NCCCN3CCN(C)CC3)c3ccccc23)cc1Cl
c: Cn1c(SCC(=O)NCc2ccccc2)nc2c([nH]c3ccccc32)c1=O
d: CC(C)N1CC2=C(C1=O)C(c1ccc(O)cc1)NC(=O)N2C
Answer: d. CC(C)N1CC2=C(C1=O)C(c1ccc(O)cc1)NC(=O)N2C
