Task: Answer the multiple-choice question.
Query: Which drug has a 8.612\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CC1=C(C#N)C(c2ccc3ncccc3c2)C(C#N)=C(C)N1
b. Cc1c(Cl)cccc1NC(=O)CCC(=O)NNC(=O)c1ccccc1
c. Cc1nc(C(F)(F)F)c(C(=O)N/N=C(\N)c2cccnc2)s1
d. O=C(C1=C(O)C(=O)N(CCN2CCOCC2)C1c1cccnc1)c1cc2ccccc2o1
Answer: a. CC1=C(C#N)C(c2ccc3ncccc3c2)C(C#N)=C(C)N1
{#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(C#N)C(c2ccc3ncccc3c2)C(C#N)=C(C)N1
CC1=C(C#N)C(c2ccc3ncccc3c2)C(C#N)=C(C)N1
