Task: Answer the multiple choice question.
Query: Which compound has a 17.375\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCN(CC)CCCN1C(=O)C(O)=C(C(=O)c2ccc(C)o2)C1c1ccc(C)o1
b: Cl.N=C(c1cccc([N+](=O)[O-])c1)N1CCCCCC1
Answer: a. CCN(CC)CCCN1C(=O)C(O)=C(C(=O)c2ccc(C)o2)C1c1ccc(C)o1
{#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}?
