Task: Answer the multiple-choice question.
Question: Which drug exhibits a -45.830\% 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 additional words.
Options:
a: COc1ccccc1N1CCN(c2nc3ccccn3c(=O)c2C=O)CC1
b: CCOc1ccc(-c2nc(CS(=O)(=O)CC(=O)NCc3ccc(F)cc3)c(C)o2)cc1
c: CC1Sc2ccc(C(=O)Nc3ccc(S(=O)(=O)N(C)C)cc3)cc2NC1=O
d: O=C(Cc1ccc(F)cc1)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
e: O=S(=O)(Nc1ncccn1)c1ccc(-n2cnnn2)cc1
Answer: d. O=C(Cc1ccc(F)cc1)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
