The correct answer is A. Nationalism.
Here's an explanation to help you understand:
1. Nationalism is the ideology or belief in the importance of preserving and promoting the interests of a particular nation. When foreign empires rule a nation, the people of that nation may feel oppressed, leading to a sense of nationalism where they seek independence and autonomy.
2. In this context, when foreign empires rule over a nation of people who have strong nationalistic sentiments, it can lead to resistance and even terrorism as a means to fight against the foreign rulers and assert their own national identity and sovereignty.
Therefore, the phenomenon of terrorism bred by foreign empires ruling a nation of people is best described by the concept of nationalism.
