Answer:
Option (c) is correct.
Step-by-step explanation:
The opportunity cost refers to the cost and benefit that is foregone by choosing some other alternative.
It was given that there is an increase in the number of jobs for women and wages also increase. Therefore, this increases the opportunity cost of doing homework because now more amount of money and job opportunities have been foregone as compared to earlier.
If a person not engaged in the household work then he would earn some money income. So, that income is foregone by choosing to do housework.
Hence, many families can hire made or specialists for their home cleaning because the cost of hiring these specialist is lower than the cost of housewife or house-husband doing that work.
