Which of the following is a common household responsibility?

Cooking is a fundamental household responsibility that pertains to the daily management of meals and nutrition for individuals and families. It involves planning, preparing, and serving food, which is crucial for maintaining health and well-being. This task often reflects cultural practices, dietary needs, and personal preferences, making it a central aspect of home management.

While other responsibilities like negotiating contracts or tax preparation can certainly be part of managing a household, they are typically less routine and may not be tasks that all households engage in regularly. Real estate management is also a more specialized area that doesn't apply to the daily domestic life of most families. Thus, cooking stands out as a universal household duty that everyone is likely to encounter regularly.
