Answer:
I don't now what is the answer of this question
Explanation:
In fern and other flowering plants, the entire leaf-bearing plant is the diploid cell. Sporophytes bear sporangia that are present exactly opposite to leaf-like appendages called sporophylls, therefore, it also a diploid.
In pteridophytes, unlike bryophytes, the main plant body is the sporophyte. The haploid gametophyte in the fern is reduced to a small but multi-cellular, inconspicuous, heart-shaped prothallus.
As archegonium is also a gametophytic body so it is also a haploid cell.
Rootstock cell is the underground part of the plant also referred to as rhizome or underground stem.
In ferns, if the rhizome is radially symmetrical, compact and short then it is referred to as rootstock. It is a diploid cell.
Spores are produced from sporangia by meiosis so they are also haploid.
Antherozoid mother cell is a sporophytic body which undergoes reduction to form spores.
A zygote is a fusion of two haploid gametes so it is a diploid.
So the correct answer is (b) six.
