Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.567\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccc(S(=O)(=O)NCc2ccc(C(=O)NCCCN3CC(C)CC(C)C3)cc2)cc1
b: COc1cccc(C2=Nn3c(nnc3-c3ccccc3O)SC2)c1
c: Cn1cc(CN(CCO)Cc2cccs2)c(-c2cccc(Cl)c2)n1
d: O=C(c1cc(N2CCOCC2)c(F)cc1[N+](=O)[O-])N1CCOCC1
Answer: d. O=C(c1cc(N2CCOCC2)c(F)cc1[N+](=O)[O-])N1CCOCC1
