Task: Answer the multiple choice question.
Question: Which compound has a 4.647\% 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: COC(=O)c1ccc(C(=O)OC)c(NC(=O)Oc2ccccc2)c1
