Task: Answer the multiple-choice question.
Question: Which compound exhibits a -8.298\% 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: O=C(NCCO)/C(=C/c1ccc(Br)cc1)NC(=O)c1cccs1
b: O=C(NCCCc1nc2ccccc2[nH]1)c1ccco1
Answer: a. O=C(NCCO)/C(=C/c1ccc(Br)cc1)NC(=O)c1cccs1
