Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.434\% 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 other words.
Options:
(a) CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccccc2)[C@H]1CCCO
(b) CCN1CCN(C(=O)c2ccc(Cl)c(S(=O)(=O)N(C)c3ccccc3)c2)CC1
Answer: a. CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccccc2)[C@H]1CCCO

Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccccc2)[C@H]1CCCO
CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccccc2)[C@H]1CCCO
