Final answer:
The correct answer is a) Real GDP per capita increases.
Step-by-step explanation:
The correct answer is a) Real GDP per capita increases.
When real GDP increases by 5 percent and the population increases by 7 percent, it means that the GDP is growing at a slower rate compared to the population growth. As a result, the real GDP per capita increases because the GDP is spreading across a larger population. Even though the overall GDP is increasing, it is not keeping up with the population growth, leading to a higher GDP per person.
