Solution

The correct option is A Monoblastic
  • Hydra belongs to the phylum Cnidaria. They are diploblastic in nature i.e, they have two body layers.
  • An outer layer called epidermis and an inner layer called the gastrodermis which lines the stomach and in between is a gel-like substance called mesoglea.

So, the correct answer is 'Diploblastic'.
