Without a visual representation of the square and line segments, it is difficult to determine which coloring represents 1/8 of the large square. However, in general, coloring 1/8 of a square would require dividing the square into 8 congruent parts and coloring one of those parts. One possible way to do this is to draw a diagonal line through the square, dividing it into two congruent triangles, and then color one of those triangles. Alternatively, one could divide the square into 4 congruent squares and color one of those squares. However, without seeing the specific arrangement of line segments, it is difficult to determine which coloring represents 1/8 of the large square.
