Answer: Option D
<u>Explanation:</u>
An underground economy refers to illegal activities that are undertaken. In prisons, the prisoners are not allowed to indulge in any relationships and also indulge in any activity that they would carry out if out of prison. In prisons, the prisoners are required to follow specific rules and norms.
If in case, the prisoners do not follow these rules and norms or do carry out these activities, they are said to be carrying out an underground economic activity. In such cases, the prisoners indulge in activities without the higher authorities getting to know of the same.
