Final answer:
The undernutrition of a 2-year-old girl in Niger can be attributed to a combination of lack of education, political instability, and bad weather conditions affecting farming, as they contribute to poverty, poor distribution of food supplies, and inadequate nutrition and health education. The correct option is d).
Step-by-step explanation:
A basic cause of the 2-year-old girl's undernutrition in Niger could be all of the above: lack of education, political instability, and bad weather conditions affecting farming. These factors often act in combination to contribute to food insecurity and undernutrition.
Poverty is both a cause and a consequence of undernutrition, creating a self-perpetuating cycle that affects individuals' health, growth, and development.
Poor access to nutritious food due to economic constraints hinders the growth and cognitive development of children. Additionally, malnutrition, which can comprise both undernutrition and overnutrition, is affected by the availability and quality of food, where undernutrition is particularly prevalent in developing countries.
Environmental factors such as bad weather can severely impact food production, which in turn leads to inadequate food supply.
Political factors like instability can disrupt food distribution and economic stability, further exacerbating the issue. Lastly, lack of education can influence food choices and the knowledge of nutrition, which is vital for health and wellbeing. Option d) is the correct one.
