Answer:
c) Nationalism.
Step-by-step explanation:
Nationalism is a sense of expressing deep support and love for one's nation. This sense of identifying oneself with one's nation, expressing all forms of appreciation and love for that nation alone, and believing in the goodness and greatness of one's nation alone becomes the basis of nationalism.
In the poem "The Soldier" by Rupert Brooke, the speaker expresses a deep belonging to his country England. He states "That there's some corner of a foreign field/ That is forever England." Not only that, the place where he's buried will be a part of England, for it housed the body of an Englishman who loved his country more than anything. The use of words like "breathing English air", "a dust whom England bore, shaped" shows his patriotic feeling and his dead body will make that burial place "a rich earth" for it conceals a "richer dust" that had once belonged to England.
Thus, the correct answer is option c.
