Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.067\% 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) CC(C)(C)c1ccc(/C=N/NC(=O)Cc2c[nH]c3ccccc23)cc1
b) O=C1N=c2ccc([N+](=O)[O-])cc2=C1c1sc(=O)[nH]c1O
Answer: b. O=C1N=c2ccc([N+](=O)[O-])cc2=C1c1sc(=O)[nH]c1O
