Task: Answer the MCQ question.
Question: Which drug exhibits a 2.158% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COC1(OC)N=C(N)C2(C#N)C(c3ccccc3)NC(C)=CC12C#N
b. O=C(c1ccco1)N1CCN(S(=O)(=O)c2ccc(S(=O)(=O)NC3CCCCC3)cc2)CC1
Answer: a. COC1(OC)N=C(N)C2(C#N)C(c3ccccc3)NC(C)=CC12C#N

Options:
{SMILES%herg_central_at_10uM%}
Answer: {%multiple_choice_result}. {SMILES#}
COC1(OC)N=C(N)C2(C#N)C(c3ccccc3)NC(C)=CC12C#N
COC1(OC)N=C(N)C2(C#N)C(c3ccccc3)NC(C)=CC12C#N
