If a cell has completed the first meiotic division and is just beginning meiosis ii

  The correct answer is :  It has half the amount of DNA as the cell that began meiosis.

Explanation:  Meiosis gives rise to four unique daughter cells, each one having half the number of chromosomes that the mother cell, this is meiosis I. During meiosis II the two cells go through four phases of division again, at this stage there the number of chromosomes in daughter cells is reduced.
