Task: Answer the multiple-choice question.
Query: Which compound exhibits a 6.189\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCN1C(=O)/C(=C/c2cccs2)N(C)C1=S
(b) N#CC(=C=[N-])/C=C(\C(=O)c1ccccc1)[n+]1ccccc1
Answer: a. CCN1C(=O)/C(=C/c2cccs2)N(C)C1=S
