c. The population increased from 70 million to 80 million.
d. The population increased from 80 million to 90 million.

D) The population increased from 80 million to 90 million.

Explanation:

if Panglossia's real GDP increased from $400 billion to $472.5 billion, it means it increased 18.13%

we must determine the real GDP per capita:

the change in real GDP per capita = ($5,250 - $5,000) / $5,000 = $250 / $5,000 = 0.05 or 5%
