Task: Answer the multiple choice question.
Question: Which drug has a 2.833\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) CCn1ncc(CN2CCCC(C(=O)Nc3cccc(-c4cc5ccccc5[nH]4)c3)C2)c1C
