Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.573\% 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 other words.
Options:
[a] CC1(C)CC(=O)C(C2c3ccccc3S(=O)(=O)c3ccccc32)C(=O)C1
[b] CN(C)/C=C/C(=O)c1ccccc1F
Answer: b. CN(C)/C=C/C(=O)c1ccccc1F
