Diploid set of Chromosomes
Explanation:
- karyotype is the characteristic of the chromosomes in a somatic cell of an individual or species, with regard to their number, size, shape, etc.
- A karyotype appear as the complete diploid set of chromosomes grouped together in pairs.
- Humans have 23 chromosome pairs = 64 chromosomes. Karyotype uses homologous chromosome pairs from metaphase as the chromosomes are duplicated and condensed.
- The karyotype is used to look determined for abnormal numbers or structures of chromosomes.
- Karyotyping is the processing of pair and order all the chromosomes of an organism.
- Karyotypes are produced using standardized staining procedures that reveal characteristic structural features for each chromosome.

B) Diploid complement display of homologous chromosome pairs is the correct answer.
- Karyotype refers to the visual representation of chromosomes present in nuclei of a cell.
- The karyotype of human cell is done to understand chromosomal abnormality with specific aim to determine change in structure or number of chromosomes that hinders growth and development.
- The representation contains 22 pair of autosomes and sex chromosomes, which will be XX in case of females and XY in case of males.
