Task: Answer the multiple choice question.
Query: Which compound has a -4.988\% 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 other words.
Options:
(a) COc1ccccc1/C=N/NC(=O)C(NC(=O)c1ccccc1)=C(C)C
(b) O=C(NCc1cccnc1)C(=O)Nc1nc(-c2ccccc2)cs1
(c) Cc1cccc(C(C)C)c1NC(=O)C1CN(S(=O)(=O)c2ccccc2)CCN1S(=O)(=O)c1ccccc1
(d) CCC(CC)NC(=O)Nc1ccccc1C(F)(F)F
Answer: a. COc1ccccc1/C=N/NC(=O)C(NC(=O)c1ccccc1)=C(C)C
{#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}?
