Sample II has the highest DNA content, which suggests it is in a stage of the cell cycle where DNA replication has occurred but cell division has not yet taken place. This is characteristic of the G2 phase prior to meiosis. Sample III has the lowest DNA content, which suggests it may be in the G1 phase prior to DNA replication, while sample I is somewhere in between and cannot be definitively identified as being in the G2 phase.
