Task: Answer the multiple-choice question.
Question: Which compound exhibits a 3.016\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CC(=O)OC[C@H]1O[C@@H](n2ccc(=O)[nH]c2=S)C(OC(C)=O)C1OC(C)=O
b. Cc1ccccc1-n1nc(C(=O)O)c(C)c(C#N)c1=O
Answer: a. CC(=O)OC[C@H]1O[C@@H](n2ccc(=O)[nH]c2=S)C(OC(C)=O)C1OC(C)=O
