Answer:
D. Basque leaders have given up all efforts to seek independence from Spain.
Step-by-step explanation:
Basques are the people who are members of the ethnic group, sharing culture and language. They do not have their own independent country but are the minorities in the countries of Southern Europe, mostly Spain and France. Because of immigration, there is a large number of Basques today also living in North America.

Basque people do have the autonomous community in Spain with Bilbao as the capital, but their quest for independence and unity of their people as the separate from Spain and France still continues
