The Correct Option is A
Solution and Explanation
In the ferns, the sexual reproduction takes place through spores which are borned in sporangia. Sporangium is a diploid structure, it bears diploid spore mother cells, which undergo produce haploid spores. Spore is the first cell of gametophyte. On germination, .it gives rise to a haploid gametophytic stage.

Concepts Used:
Pteridophytes
Pteridophytes are the first terrestrial vascular plants. Carolus Linnaeus classified them under the group cryptogamae. Pteridophytes occupy a transitional position between bryophytes and spermatophytes.
For Example, Silver fern, Equisetum, Selaginella
The general characteristics of Pteridophytes are:
- They are seedless.
- They are multicellular.
- They reproduce through spores.
- They are independent and free-living organisms.
- They have a well-differentiated plant body into root, stem and leaves.
