The correct answer is - agriculture.
The agriculture is the biggest user of the freshwater on a global scale. It accounts for almost 70%, or more precisely 69%, of the total usage of freshwater in the world. The industry is also a big user, with approximately 19%, and the households and the municipal usage is around 12%.
The agriculture is by far the biggest user of freshwater because the arable land is massive, and it continuously expands. That means that the amount of plants is bigger, and constantly growing, and most of those plants are plants that require much more water than what the nature provides in the place where they are grown.
