Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.371\% 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) CC(OC(=O)CC(NC(=O)c1ccccc1Cl)c1ccccc1)C(=O)Nc1cccc(Cl)c1Cl
(b) Br.CCn1c(=N)n(CC(=O)c2ccc(OC)cc2)c2ccccc21
Answer: a. CC(OC(=O)CC(NC(=O)c1ccccc1Cl)c1ccccc1)C(=O)Nc1cccc(Cl)c1Cl
