The correct answer is - d. the wall marked the northern defensive boundary of Roman Britain.
The Hadrian wall was built under the rule of the Emperor Hadrian, after whom it got its name. The Roman emperor ordered the building of this wall because of the Pictish tribes from Scotland, which were constantly entering the northern parts of the territory of Roman Britain and were robbing the people.

A human community with high population density and low economic status will have the highest birthrates.
Explanation:
A is not correct because usually, these are populations in countries that are transitioning from one political to another political model, and these populations actually tend to decline, mostly because of immigration.
B is not correct because such populations tend to have low birthrates, often even below the bar for simple replacement of the population.
C is not correct because such populations tend to live in very bad conditions, so despite having relatively high birthrates, they stagnate in their growth.
D is correct because such populations have both the numbers needed and also live in more traditional societies, leading to very high birthrates, as can be seen with Nigeria, Ethiopia, Pakistan, Indonesia, etc.
