Answer:
The correct answer is letter "A": Robert is not part of the labor force.
Explanation:
In this case, we cannot consider Robert in any part of the unemployment figure because he is not actively looking for a job. He would be considered at least unemployed if he would be seeking for work, but he is not. His activities at home do not have any type of monetary retribution since he is looking after his own children. In the same sense, he cannot be considered underemployed since in this category fall mainly professionals holding a degree who for certain economic, political or social issues do not work in a field related to their studies. The latest is not the case of Robert, either.
