Answer:
C. Lower life expectancies
Step-by-step explanation:
Developing countries are those that are, by the index of the development, have not reached yet high enough industrial phase as other countries. They tend to have lower GDP and worst life conditions (education, health care, family care, bad infrastructure, etc.)
By the Human Development Index, these countries include almost whole Latin America, most of Asia, Eastern Europe, and parts of Africa.
Because of bad living conditions, people in these countries will more likely have a lower life expectancy. This mainly has to do with healthcare which is not considered as good as in developed countries. Medical staff can be unskilled, there might be a lack of instruments, and the health might be more expensive.
One of the reasons is also education – when people are less educated, they are expected to do less paid jobs, which leads to a higher level of poverty. This ends up in more poor people who can support themselves and can provide for life.
Developing countries also might have the bad infrastructure, which leads to more road accidents. There might be more accidents in general as care and protection is not as developed and progressed as needed.
