Task: Answer the multiple-choice question.
Question: Which compound exhibits a 7.564\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCCCN(CC)C(=O)Cn1cnc2ccc(S(=O)(=O)N3CCC(C)CC3)cc2c1=O
b: CCC(CO)N=CC1=C(O)C(C(=O)c2ccccc2)CCC1=O
Answer: b. CCC(CO)N=CC1=C(O)C(C(=O)c2ccccc2)CCC1=O
