Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.479\% 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 other words.
Options:
a: COc1ccccc1CCNS(=O)(=O)c1cn(C)nc1C
b: CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](c2ccc3c(c2)OCO3)[C@H]1CCCO
c: NC(=O)c1cc([N+](=O)[O-])ccc1NCc1ccc(F)cc1
d: CCOc1ccc(NC(=O)N2CCC(c3nc4ccccc4o3)CC2)cc1
e: O=C(O)c1cn[nH]c1-n1cnnn1
Answer: b. CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](c2ccc3c(c2)OCO3)[C@H]1CCCO
{#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#}
CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](c2ccc3c(c2)OCO3)[C@H]1CCCO
CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](c2ccc3c(c2)OCO3)[C@H]1CCCO
