Task: Answer the multiple-choice question.
Query: Which drug has a 4.052\% 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] NC(N)=NC1=NC(=O)/C(=C/c2ccccc2-n2cccn2)S1
[b] Cn1ncc([N+](=O)[O-])c1C(=O)Nc1ccc(-c2nc3ccccc3[nH]2)cc1
Answer: b. Cn1ncc([N+](=O)[O-])c1C(=O)Nc1ccc(-c2nc3ccccc3[nH]2)cc1
