Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.668\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCN(CC1CCCN(CCc2cccc(OC)c2)C1)C(=O)c1ccc(COC)o1
b: COC(=O)c1sc(NC(=S)NC(=O)c2cccc(C)c2)nc1C
Answer: b. COC(=O)c1sc(NC(=S)NC(=O)c2cccc(C)c2)nc1C
