Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.228% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) C/C(=N\Nc1nncc2ccccc12)c1ccc(Cl)c([N+](=O)[O-])c1
(b) Cn1c2ccccc2n2c(=O)c(Cl)c(-c3ccccc3)c(C#N)c12
Answer: b. Cn1c2ccccc2n2c(=O)c(Cl)c(-c3ccccc3)c(C#N)c12
