The correct answer is C.

This is a double matrices problem. The categories should be Male, Female, Union, and Not Union.
Assume 100 people total to make the problem easy.
Therefore, there is 46 total male and 54 total female.
You can also conclude that there are 60 total workers in union and 40 not in union.
Since 70% of the 60 workers in the union are male, that means there are 42 male union workers and 18 female union workers.
Now you can conclude that the percentage of female workers not in a union is 54 - 18 = 36
