Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.036\% 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: Cc1cc(C)cc(NC(=O)C2CCCN(S(=O)(=O)c3cnc[nH]3)C2)c1
b: COCC(C)NCc1cccc([N+](=O)[O-])c1.O=C(O)C(=O)O
c: c1cncc(-c2nnc(-c3cccnc3)nn2)c1
d: CCCc1nc2ccccc2c(C(=O)OCc2nnc(-c3cc(OC)c(OC)c(OC)c3)o2)c1CC
Answer: b. COCC(C)NCc1cccc([N+](=O)[O-])c1.O=C(O)C(=O)O
