Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.769\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(NCc1ccccc1Cl)C1CCN(S(=O)(=O)N2CCCCC2)CC1
[b] COc1ccc(C)cc1NC(=O)Cn1cnnn1
Answer: a. O=C(NCc1ccccc1Cl)C1CCN(S(=O)(=O)N2CCCCC2)CC1
