Task: Answer the multiple choice question.
Question: Which drug has a 7.407\% 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] CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](c2coc3ccccc3c2=O)[C@@H]1CCCO
[b] Nn1c(Nc2ccccc2)nc2ccccc2c1=O
Answer: b. Nn1c(Nc2ccccc2)nc2ccccc2c1=O
