Review the map, which relates to voyages sponsored by Prince Henry.

An untitled map of Africa. An area along the northwest coast is shaded.

What does the shaded area show?

the route Europeans followed to get around Africa to Asia
the spread of Christianity due to European exploration
areas where Europeans created new settlements
areas people were taken from to be enslaved by Europeans

The shaded area most likely represents the areas where Europeans created new settlements along the northwest coast of Africa, particularly related to voyages sponsored by Prince Henry. This could have been part of the exploration and colonization efforts by the Portuguese during the Age of Discovery.
