(A) The dark-stained body observed near the nuclear membrane in interphase cells is known as a Barr body.Barr bodies represent inactivated $X$-chromosomes in cells with more than one $X$-chromosome.The number of Barr bodies in a cell is calculated using the formula: $N = (	ext{Number of } X	ext{-chromosomes}) - 1$.For an individual to have a visible Barr body, they must have at least two $X$-chromosomes (e.g., $XX$, $XXY$, $XXX$).Among the given options, $XX$ is the only genotype that possesses two $X$-chromosomes, resulting in $2 - 1 = 1$ Barr body.
