The correct option is C It is eaten up or degenerates
The tapetum is a layer of nutritive cells found
within the sporangium, particularly within the anther of flowering plants. It
is important for the development of pollen grains. It is involved in the
formation of pollen wall. It helps to transport the nutrients to
the inner side of the anther. Tapetum gets degenerated on
maturity.
So, the correct answer is option C.
