Solution

Answer : The correct answer is B . Plasmogamy is the the first stage in the sexual reproduction of fungi in which the cytoplasm of two sex cells fuse with each other resulting in the formation of nucleate cell or dikaryon.

Supplementary information : Sexual reproduction occurs in all the groups of fungi except in deuteromycetes. The sexual reproduction in fungi completes in three stages,

A.plasmogany ; it is the first stage in the sexual reproduction in which the cytoplasm of two sex cells fuse with each other resulting in the formation of nucleate cell or dikaryon

B. karyogamy : involves the fusion of two compatible nuclei brought together as a result of plasmogamy. The resulting diploid nucleus is called synkaryon

C. meiosis: diploid nucleus divides by meiosis resulting in the formation of haploid nuclei which is usually occurs immediately after the fusion of two nuclei.
