To determine which country would be considered the most developed based on life expectancy and infant mortality rate, we can evaluate the provided options as follows:
- Country A: Life expectancy of 75 years and infant mortality rate of 8 deaths per 1,000 live births.
- Country B: Life expectancy of 79 years and infant mortality rate of 8 deaths per 1,000 live births.
- Country C: Life expectancy of 79 years and infant mortality rate of 6 deaths per 1,000 live births.
- Country D: Life expectancy of 75 years and infant mortality rate of 6 deaths per 1,000 live births.
Analysis:
- Higher life expectancy generally indicates better health, living conditions, and access to healthcare.
- Lower infant mortality rates indicate better healthcare for mothers and infants, as well as overall better living conditions.
From the options, we can evaluate:
- Country C has the highest life expectancy (79 years) and the lowest infant mortality rate (6 deaths per 1,000 live births).
- Country B has a higher life expectancy than A but the same infant mortality rate (8 per 1,000).
- Country D has the same life expectancy as A but a lower infant mortality rate (6 deaths per 1,000).
Considering both factors, Country C would be considered the most developed due to its higher life expectancy and lower infant mortality rate.
Conclusion: The most developed country based on the criteria is the third option: "A country with a life expectancy of 79 years and an infant mortality rate of 6 deaths per 1,000 live births."
