The Correct Option is D

Solution and Explanation

Dikaryon is a stage/phase of a cell, in which, there are two nuclei. This condition arises, if fusion of cytoplasm (plasmogamy) is not immediately followed by fusion of nuclei (karyogamy), i.e., there is a delay between them. Such cells are called dikaryotic cells. This condition is found in higher fungi where karyogamy is delayed (with respect to plasmogamy) and is called dikaryophase.

Biological Classification

The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
