Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.633\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(NC1CCSc2ccccc21)c1cc(S(=O)(=O)N2CCOCC2)ccc1Cl
[b] COc1ccc(OC)c(NC(=O)CN2C(=O)C3(OCCCO3)c3ccccc32)c1
Answer: a. O=C(NC1CCSc2ccccc21)c1cc(S(=O)(=O)N2CCOCC2)ccc1Cl
