Task: Answer the multiple-choice question.
Question: Which compound exhibits a 21.053\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC(=O)C1C2c3ccccc3OC1(C)N=c1s/c(=C/c3cn(C)nc3C)c(=O)n12
[b] CC1(C)CC(=O)C2=C(C1)N(N1CCOCC1)C(N)=C(C#N)C2c1cccnc1
[c] Fc1ccc(N2CCN(Cc3ccc4c(c3)OCO4)CC2)cc1
Answer: b. CC1(C)CC(=O)C2=C(C1)N(N1CCOCC1)C(N)=C(C#N)C2c1cccnc1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?

Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CC1(C)CC(=O)C2=C(C1)N(N1CCOCC1)C(N)=C(C#N)C2c1cccnc1
CC1(C)CC(=O)C2=C(C1)N(N1CCOCC1)C(N)=C(C#N)C2c1cccnc1
