(B) Klinefelter syndrome is a genetic condition characterized by the presence of an extra $X$ chromosome in males,resulting in a genotype of $47, XXY$.Barr bodies are inactive $X$ chromosomes found in the somatic cells of individuals with more than one $X$ chromosome.The formula to calculate the number of Barr bodies is $N - 1$,where $N$ is the total number of $X$ chromosomes.For Klinefelter syndrome $(XXY)$,$N = 2$.Therefore,the number of Barr bodies = $2 - 1 = 1$.
