Task: Answer the multiple choice question.
Question: Which compound exhibits a -16.865\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CN1CCN(C/C(=C2/N=C(c3ccccc3)OC2=O)N(C)C)CC1
b: CCN(C(=O)CCCCC(=O)N(CC)c1ccccc1)c1ccccc1
Answer: a. CN1CCN(C/C(=C2/N=C(c3ccccc3)OC2=O)N(C)C)CC1
