Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.966\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccc(NC(=O)COC(=O)CC2CCCCC2)cc1
b: O=C(N/N=C/c1sc(N2CCOCC2)nc1-c1ccccc1)c1ccccc1Cl
Answer: b. O=C(N/N=C/c1sc(N2CCOCC2)nc1-c1ccccc1)c1ccccc1Cl
