    D)  lt has more cytoplasm and more DNA than an uncleaved zygote

    Correct Answer: D

    Solution :

    Cleavage divisions are mitotic division, in which the single celled zygote is converted into a multicellular morula.

So, the DNA content will increase, but there is no increase or insignificant increase in amount of protoplasm.
