The correct option is D Only I, III and IV
Cytotaxonomy is the classification of organisms based on cytological characters like chromosome number, morphology and chromosomal behaviour during meiosis between different taxons. Based on the position of centromere in the chromosome, there are different types of chromosomes. Also, cytotaxonomy is one of the aids used for phylogenetic classification when it’s difficult to find fossils.
