Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.091% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] Cn1c(=O)c2[nH]c(Nc3ccccc3)nc2n(C)c1=O
[b] COc1ccc2nc(NCCCNC(=O)c3cc(OC)c(OC)c(OC)c3)c(C#N)cc2c1
Answer: a. Cn1c(=O)c2[nH]c(Nc3ccccc3)nc2n(C)c1=O
