Option D Service Jobs, is the right answer.
World War II created a notable influence on the Economy and workforce in the United States. The augmentation of service employment contributed essentially to the growth of female employment throughout the post-World War II period, but the rise in female labor force cooperation was not a significant factor in either the expedition of employment or the slowdown of productivity growth in 1961-76. The growth of Government employment was a contribution of the Service sector. The expansion of government employment has been quite modest, apart from changes in the industry mix.
