The statement that best explains the differences between countries with higher and lower percentages of women working in agriculture is:
Option D: Countries with large percentages of female employment in agriculture tend to be mostly rural and are reliant on subsistence agriculture.

In contrast, in more urbanized or industrialized areas, there may be fewer women engaged in agricultural work due to different economic structures and job opportunities.
