Task: Answer the multiple-choice question.
Query: Which drug exhibits a -5.542% 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) Cn1nc(C(=O)Nc2cc(Cl)ccc2N2CCCC2)c2ccccc2c1=O
