Answer:
The answer is C - It represents only one speaker
Step-by-step explanation:
Lyrical poetry is used to express the emotion and feelings of the author. However, that does not always mean the author will refer to his/her literal self within said poetry, eliminating D. Because lyrical poetry expresses ones inner emotions, that also means that it won't always be a happy, up-beat subject, eliminating B. Option A is eliminated as well, since nothing about the meaning of lyrical poetry indicates that it must have some sort of heroic meaning or trail within it.
This is my best explanation of it, hope this helps!
