Task: Answer the multiple choice question.
Question: Which drug has a 12.966\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)CCC1OC(=O)C(O)=C1c1ccccc1
[b] O=C1NCC2=C1C(c1ccccc1)Nc1ccccc1N2
Answer: b. O=C1NCC2=C1C(c1ccccc1)Nc1ccccc1N2
