The answer is A
Explanation:
Cells of living organisms contains nuclear material which is usually found as CHROMOSOMES. However, scientists have devised a means to check for the number and arrangement of chromosomes in a cell. This means is called KARYOTYPING. A Karyotype is the pictorial display of an individual's chromosome. It shows the number and arrangement of chromosomes in that particular cell.
Based on this, karyoptying can be used to detect if a chromosome is missing or extra in the set. These cases of missing or extra copies of chromosomes are genetic or chromosomal disorders that have been caused by MUTATION. A Karyotype can show if there has been any change in number or arrangement of a chromosome that have led to a genetic disorder or abnormalities.
