Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
In fungi Sexual reproduction decrease in complexity because as we go from Phycomycetes to Basidiomycetes sex organs are eliminated and fusion of protoplasm occurs by fusion of two somatic cells of different genotype.
In algae, sexual reproduction increases in complexity from lower to higher forms as Chlorophyceae reproduces sexually by the formation of sex cells, in Phaeophyceae reproduction may be isogamous, anisogamous or oogamous, red algae reproduces sexually followed by complex post fertilisation events.
So the correct option is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
