Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.150\% 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: Cc1ccccc1C=Nc1ccccc1C(N)=O
b: CSc1ncc(CN2CCCCC2C(=O)Nc2ccc(Oc3ccccc3)nc2)cn1
Answer: a. Cc1ccccc1C=Nc1ccccc1C(N)=O
