Answer:
C. Both enjoy life and both will die
Step-by-step explanation:
The first three stanzas of the poem show how man and the fly enjoy their lives in different ways, but they enjoy what life offers them and even if they are having fun, they will both die at some point, neither of them can escape death. This comparison shows that fly and man are not so different, as it may seem, since both will have the same end.
The line "For I dance and drink and sing, till some blind hand shall brush my wing," makes this conclusion much more evident.
