Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -3.644\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)c1ccc(/C=N/Nc2ccc(S(=O)(=O)N3CCCC3)cc2[N+](=O)[O-])cc1
[b] CC1(C)COC(c2ccc(F)c([N+](=O)[O-])c2)=N1
Answer: b. CC1(C)COC(c2ccc(F)c([N+](=O)[O-])c2)=N1
