Task: Answer the multiple-choice question.
Query: Which compound exhibits a 21.171% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(O)CCn1cc(C(=O)O)c(-c2ccccc2)n1
b C/C(CCc1ccccc1)=N\NC(=O)c1ccccc1[N+](=O)[O-]
Answer: b. C/C(CCc1ccccc1)=N\NC(=O)c1ccccc1[N+](=O)[O-]
