Which of the following are water intensive crops?

When fossil fuels burn in a limited supply of oxygen, incomplete combustion occurs, leading to the formation of carbon monoxide ($CO$). Carbon monoxide is a highly toxic, colorless, and odorless gas. It binds with hemoglobin in human blood to form carboxyhemoglobin, which is far more stable than oxyhemoglobin. This severely reduces the oxygen-carrying capacity of the blood, leading to hypoxia and potentially death. Carbon dioxide ($CO_2$), nitrogen dioxide ($NO_2$), and sulphur dioxide ($SO_2$) are also pollutants, but carbon monoxide is directly and acutely poisonous to aerobic life forms.
