Answer:
D. cotton
Step-by-step explanation:
Cotton, as a cash crop, is very important to the country of Uzbekistan. The harvesting of cotton is controlled by the state and many of the people are involved in such activity, including children. Due to this, the country had long been scrutinized. However, according to the Ministry, such action is considered "child work" and not child labor because the children are just contributing to the well-being of the family and the economy of the country, thus, it becomes a tradition for them to harvest the crops.
