Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.681\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1ccc(OCc2nnc(-c3ccc(Cl)cc3)o2)cc1
b: Cc1ccc(S(=O)(=O)NC(C)(C)C)cc1C(=O)OC(C)C(=O)NC1CC1
c: C=CCOc1c(Br)cc(CNn2cn[nH]c2=S)cc1OC
d: COCC(C)NC(=S)Nc1ccccc1[N+](=O)[O-]
Answer: d. COCC(C)NC(=S)Nc1ccccc1[N+](=O)[O-]
