Problem statement: Answer the multiple-choice question.
Question: Which compound has a -3.438\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(NCc1ccccc1)N1CCC(n2cnc3cc(F)ccc32)CC1
[b] N/C(Cc1ccc([N+](=O)[O-])cc1)=N\OC(=O)c1ccc(Br)cc1
Answer: b. N/C(Cc1ccc([N+](=O)[O-])cc1)=N\OC(=O)c1ccc(Br)cc1
