Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.550% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COC(=O)c1ccc(CS(=O)(=O)c2ccc(F)cc2)o1
b: CC(=O)Nc1c(-c2ccc3ccccc3c2)nc2ccccn12
Answer: a. COC(=O)c1ccc(CS(=O)(=O)c2ccc(F)cc2)o1
