Task: Answer the multiple choice question.
Question: Which compound has a 21.078\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CSc1ccc(C(=O)C2CCCN(Cc3cc4ccccc4[nH]3)C2)cc1
b: Cc1ccc(C(=O)NCCNS(=O)(=O)c2ccccc2[N+](=O)[O-])cc1
c: CN1CCN(C(=O)c2ccccc2NC(=O)c2cccs2)CC1
d: CC(/C=N/NC(=O)c1cc(-c2ccc(Cl)cc2)nc2ccccc12)=C\c1ccco1
e: O=C1NC(=O)C(CC(=O)N(Cc2ccco2)C2(C(=O)NC3CCCC3)CCCCC2)N1
Answer: d. CC(/C=N/NC(=O)c1cc(-c2ccc(Cl)cc2)nc2ccccc12)=C\c1ccco1

Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CC(/C=N/NC(=O)c1cc(-c2ccc(Cl)cc2)nc2ccccc12)=C\c1ccco1
CC(/C=N/NC(=O)c1cc(-c2ccc(Cl)cc2)nc2ccccc12)=C\c1ccco1
