In the poem, the speaker's losses are exaggerated (hyperbole) to finally lead up to the greatest loss is Irony. The correct answer is option is C.
Irony is a literary device where there is a contrast between what is expected to happen and what actually occurs. In this context, the speaker's losses being exaggerated throughout the poem create an expectation or impression of significant, perhaps insurmountable, difficulties. The reader is led to believe that these losses are the focal point.
However, the ironic twist comes when the poem reveals that these exaggerated losses were leading up to a single, even greater loss. The exaggeration serves as a tool to mislead or heighten the impact of the actual, ultimate loss. The contrast between the expected magnitude of the losses and the revelation of an even greater loss is what makes it ironic.
For example, if the poem describes a series of seemingly terrible events, making the reader think those are the worst things that could happen, and then concludes with an even more devastating event, that would be an example of irony. The exaggeration of the initial losses creates a sense of surprise or reversal when the true extent of the speaker's situation is revealed.
