Problem statement: Answer the multiple-choice question.
Question: Which compound has a 8.188\% 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(O)C(F)(F)F.O=C1C(Cc2ccccc2)Nc2ncnc(N3CCOCC3)c2N1Cc1ccc(Cl)cc1
[b] CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccccc3)CC2)=C[C@H](c2csc3ccccc23)[C@H]1CCCO
Answer: b. CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccccc3)CC2)=C[C@H](c2csc3ccccc23)[C@H]1CCCO
