Task: Answer the multiple choice question.
Question: Which drug has a 6.097\% 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(=O)c1ccc(N2CSC3=C(C#N)C(c4ccc(OC)cc4OC)CC(=O)N3C2)cc1
[b] CN1C(=O)C2(Oc3ccccc3C3CC(c4ccccc4)=NN32)c2ccccc21
Answer: b. CN1C(=O)C2(Oc3ccccc3C3CC(c4ccccc4)=NN32)c2ccccc21
