Correct Answer: Option D

Explanation

Humans have 23 pairs of chromosomes in total, out of which 22 pairs are autosomes. Autosomes are chromosomes that are not involved in determining the sex of an individual. The remaining pair of chromosomes is the sex chromosomes, which determines the sex of an individual. Therefore, the total number of autosomes in humans is 44. Autosomal abnormalities can lead to genetic disorders such as Down syndrome, Turner syndrome, and Klinefelter syndrome. It is essential to understand the number and structure of chromosomes in humans for diagnosing such disorders.
