The correct answer is A.
Current demographic structures in developed countries are mainly characterized by large shares of elderly population. Moreover, the task of taking care of the old ones in the family was undertaken by women until 50-60 ago, as most of them did not participate in the labor force. But, nowadays most of the working age population are actually employed or seeking for a job and cannot perform these tasks.
Therefore, this is why this occupation of home health care aider, together with the flourishment of nursing homes, are the current ways of taking care of those who cannot live by themselves.
