Task: Answer the multiple choice question.
Query: Which drug has a 0.681\% 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) CCOC(=S)N/C(=N\S(C)(=O)=O)c1ccccc1
(b) Cc1cc(C)n(-c2ccc(S(=O)(=O)N3CCOCC3)cc2[N+](=O)[O-])n1
Answer: a. CCOC(=S)N/C(=N\S(C)(=O)=O)c1ccccc1
