Task: Answer the multiple choice question.
Question: Which compound has a 4.246\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(O)c1ccc(CSc2nc(-c3ccccc3)cc(C(F)(F)F)n2)cc1
[b] CCOC(=O)C1CCN(C(=O)CN(c2ccc(Oc3ccccc3)cc2)S(C)(=O)=O)CC1
Answer: b. CCOC(=O)C1CCN(C(=O)CN(c2ccc(Oc3ccccc3)cc2)S(C)(=O)=O)CC1
