Task: Answer the multiple choice question.
Query: Which compound has a -5.505% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CC(C(=O)NC1CCCC1)N1CCN(S(=O)(=O)c2ccc(C(C)(C)C)cc2)CC1
b: CCC(=Nc1ccc(OC)cc1OC)c1c(O)n(C2CCCCC2)c(=O)[nH]c1=O
Answer: b. CCC(=Nc1ccc(OC)cc1OC)c1c(O)n(C2CCCCC2)c(=O)[nH]c1=O
