    B) Shape of the subunits in the DNA molecule

    Explanation:

    The question wants to know what the expression is directly dependent on.

    The sequence of genetic expression goes like this:

    DNA - > RNA - > protein

    If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.

    So

    Shape of subunits in DNA - > Sequence of bases coded for by the ribosome with RNA - > Arrangement of amino acids in the protein synthesized.

    Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.
