Final answer:
Based on the given information regarding GDP per capita, political stability, and human trafficking, the Central African Republic would be the poorest among the options listed.
Step-by-step explanation:
The statement suggests that longer lifespans are generally associated with richer nations. If we consider the given countries and their respective economic statuses, based on data provided by LibreTexts, the Central African Republic has a notably low GDP per capita, which is defined as the total output of a country divided by the number of people, and also faces challenges such as political instability and issues related to human trafficking. Calculations of GDP per capita can provide insights into the average economic output per person, and hence reflect the general wealth of the country's inhabitants, which in turn is correlated with lifespan. The GDP per capita for the Central African Republic, considering its GDP of 1,107,689 million CFA francs and a population of 4.862 million with an exchange rate of 284.681 CFA francs per dollar, indicates it is the poorest among the options provided.
