Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.551\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COC(=O)C[C@H]1c2cc(F)ccc2S(=O)(=O)N1Cc1ccccc1OC
b: CCOc1ccc(/C=C(/NC(=O)c2ccccc2Cl)C(=O)O)cc1
c: Cc1nc(NC(=O)COC(=O)CCc2nc3ccccc3s2)c(Cl)cc1Cl
d: Cc1ccc(C(C[N+](=O)[O-])c2c(C)[nH]n(-c3ccccc3)c2=O)cc1
Answer: d. Cc1ccc(C(C[N+](=O)[O-])c2c(C)[nH]n(-c3ccccc3)c2=O)cc1
