- Consumption: This refers to the act of using goods and services to satisfy personal needs and wants. It doesn't involve earning money directly.

- Leisure: This is the time spent away from work, or other necessary activities like cooking. It’s about relaxation and enjoyment, not making money.

- Work: This is a purposive human effort that is distinguished from other social activities because it typically involves a level of skill or exertion and leads to monetary compensation. Work is done with the intention of earning income.

- None of the above: This option is not applicable here, as one of the above clearly describes the activity involving monetary compensation.
