Task: Answer the multiple choice question.
Question: Which drug has a -0.348\% 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 additional words.
Options:
a: CCOC(=O)c1cc(C)nn1-c1nc(Cl)cc(OC)n1
b: Cc1ccc(CC(=O)Nc2cc(C)ccn2)cc1
Answer: a. CCOC(=O)c1cc(C)nn1-c1nc(Cl)cc(OC)n1
