Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.188\% 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 O=C(CSc1nnc(Cc2cccs2)n1Cc1ccco1)Nc1ccc(Cl)cc1Cl
b CCN=C(NCC)SC1CC(=O)N(c2cccc(OC)c2)C1=O
Answer: b. CCN=C(NCC)SC1CC(=O)N(c2cccc(OC)c2)C1=O
