Answer:  To remove bias when estimating the proportion of working adults living in urban, suburban, and rural areas.

Explanation: In simple words, stratification refers to the process in which different sections of the society are grouped on the basis of one or more general factors.

In the given case, the company wants to estimate the minutes of working adults in the region and the region is grouped into urban, suburban and rural.

Thus, the random selection from different regions is done so that no bias takes place regarding the number of adult working in these three different areas.
