Solution

The correct option is A Synangium
  • Synangium is a three chambered or trilocular spore bearing structure in a pteridophyte Psilotum. Hence, synangium is a triad of sporangia.
  • Jacket cells are the sterile cells around the spermatogenous tissue in the antheridium.
  • Tapetum is the innermost layer of microsporangium which provide nutrition to the microspore mother cells.
So, the correct answer is 'Synangium'.
