Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 6.912\% 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 other words.
Options:
a. CNc1ccc(NC(C)=O)cc1[N+](=O)[O-]
