Hint: The fungi of this specific phylum is generally reproduced by the sexual mode of reproduction. And the spores formed by the fungi are directly stored in the basidia so they belong to the basidiomycota group of the fungus.

Complete answer:
1.In this specific group of the fungi club fungi , two different hyphae come close to each other and result in the primary fusion and form a club-like structure.
2.This club-like structure is commonly known as the basidium.
Firstly these club fungi form asexual spore by the process of budding these spores are generally haploid .
3.After the formation of basidia these spores are transferred to the basidia here two haploid spores fuse with each other and give rise to a diploid zygote .
4.This again undergoes meiosis type of division and forms 4 haploid cells with each cell have its own separate nucleus.
5.Then these cells get migrated towards the terminal of the basidia and result in the formation of four individual projections and these new projections are separated by the cell wall to form the spore.
6.When the two individual hyphae got fuse with each other then the sage of dikaryotic obtained in the basidia as these both hypha have it’s separate nucleus and then the basidia have two nucleus this stage is prolonged and results in the formation of fruiting body.

So here both assertion and reason are correct and reason is the correct explanation of assertion.

Hence the correct answer is OPTION(A)

Note: Some example of basidiomycota are mushroom , boletales, gilled mushroom
Club fungi are commonly found after rain, on supermarket shelves and growing in our lawns.
