Dear student,
Please find below the solution to the asked query
The correct option is (1).
The male shield fern (Dryopteris) is found in moist shady places. It has large leaves called fronds. The sori (cluster of sporangia) is covered by membranous sheath called true indusium. When spores germinate, they produce small thalloid gametophyte called prothallus that bears antheridia and archegonia. The antheridia produce sperms that are multiflagellate.
Hope this information will clear your doubts about the life cycle of male shield fern.
