Apparently with no surprise,

To any happy flower,
The frost beheads it at its play,
In accidental power.
The blond assassin passes on.
The sun proceeds unmoved,
To measure off another day,
For an approving God.

In the above poem, which of the following might the frost symbolize?

Cold
Depression

death

Correct.

In the poem, the frost might symbolize death. To arrive at this conclusion, let's analyze the description of the frost in the poem. The poem states that the frost beheads the happy flower at its play with accidental power. This suggests that the frost has the ability to abruptly end the flower's life, just as death can end a person's life unexpectedly. Additionally, the adjective "assassin" is used to describe the frost, implying that it brings about death. Therefore, based on these clues, we can interpret the frost in the poem as a symbol of death.
