Looking at the graph, we can see that the value of f(1990) is approximately 60 million and f(2000) is approximately 76 million. Therefore, f(2000) - f(1990) is approximately 16 million. This means that the number of women in the workforce increased by approximately 16 million from 1990 to 2000. Thus, the answer is D.
