Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.820% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCOC(=O)N1CCN(C(=O)CS(=O)(=O)c2cn(Cc3ccccc3Cl)c3ccccc23)CC1
b: CCCC(=O)Nc1ccc(-c2nc3cc(C)ccc3o2)cc1
Answer: a. CCOC(=O)N1CCN(C(=O)CS(=O)(=O)c2cn(Cc3ccccc3Cl)c3ccccc23)CC1
