<span>B Experts today estimate 20,000-30,000 laborers worked on the pyramid at any one time.
This is the best option out of all the options. The statement should support the idea that many people were needed to build the pyramid.

Option B is a clear estimate of the tens of thousands of workers necessary to build a pyramid.
