d. Monosomy X is the only viable monosomy known to occur in humans.
Explanation:
Human have 22 pair of homologous chromosomoses and an extra pair of sex chromosomes. While in males the sex chromosomes are X and Y , females have two chromosomes X . Anyway, in normal conditions the total number of chromosomomes that humans have in their cells is 46 (23 pair of chromosomes).
Aneuploidy is a biological condition where an individual have an abnormal number of chromosomes in their cells. In humans for examples, this would be a human having more or less than 46 chromosomes.
The Turner syndrome also called monosomy X is an aneuploidy where one of the X chromosomes is missing in a female. Although under constant supervision, people with Turner syndrome have viable healthy lives. However this is the only monosomy that occur in humans that is compatible with life.
