Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.896\% human ether-à-go-go related gene (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. O=C(NCc1ccccc1)Nc1cccn(Cc2ccccc2)c1=O
b. O=C(Cc1cccs1)Nc1ccccc1F
Answer: a. O=C(NCc1ccccc1)Nc1cccn(Cc2ccccc2)c1=O
