Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -23.775% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C1C2=C(c3ccccc31)[N+](=O)C1CCCCC1N2[O-]
b O=C(/C=C/c1c(Cl)nc2ccccn12)Nc1ccc(F)cc1
Answer: a. O=C1C2=C(c3ccccc31)[N+](=O)C1CCCCC1N2[O-]
