Problem statement: Answer the multiple choice question.
Question: Which drug has a -21.359\% 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) NC(=O)c1ccccc1N/C=C1\CCCCC1=O
b) CCN1C(N(C)CCc2cccs2)=N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
Answer: b. CCN1C(N(C)CCc2cccs2)=N[C@@H](c2ccccc2)C(C(=O)OC)=C1C

Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCN1C(N(C)CCc2cccs2)=N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
CCN1C(N(C)CCc2cccs2)=N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
