The correct answer is (d) South Korea.
In 1996, South Korea had the highest percentage of economically active women (excluding students and those doing domestic duties in their homes) as a percentage of all women of working age. South Korea has made significant progress in women`s workforce participation and has implemented various policies and initiatives to encourage women`s employment and career development.
While other countries like the USA, China, and Russia have also seen increases in women`s workforce participation, South Korea had a particularly high rate in 1996. It`s important to note that these statistics may have changed over time as economic and social conditions evolve in different countries.
