Task: Answer the multiple-choice question.
Query: Which compound exhibits a 9.168\% 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, b, or c without using any additional words.
Options:
a. Cn1c(C(=O)NN)cc2cc(OCc3ccccc3)ccc21
