Solution
The correct option is A A chromosomal disorder
The majority of human chromosomal abnormalities occur in the autosomes and some of which are caused by the mutations and resultsdue to missing, of entire chromosomes, or large segments of them, are duplicated, or otherwise altered. It may cause some serious implication physically but are survivable. For example, Trisomy of the 21 st chromosome causes Down's syndrome (45+XY/45+XX). It is characterized by round face, broad forehead and palmer crease with low intelligence. Thus, the correct answer is option A.
