The correct answer is B) love of country.
The quote from Garibaldi suggests that nationalism is closely tied to other characteristic: love of country.
The idea of nationalism implies the love of country. Nationalist people consider primarily the concerns of its country and its citizens. They defend their culture, its traditions, its bloodline, among other things. Garibaldi expresses the idea in correct terms when he said: “let him who loves his country in his hear and not from his lips only, follow me.” Nationalist wants to protect its country from foreign influences.
