The surface of the villi in the small intestine is covered by a single layer of epithelial cells called enterocytes. Enterocytes absorb nutrients from the intestinal lumen as they move up the side of the villus. The enterocytes are shed from the end of the villus through apoptosis after 3 to 4 days. Consequently, new cells must be continuously supplied from the crypt and move up the villus. When a stem cell in the crypt divides, what are its immediate daughter cells?

A. a transit amplifying cell and a goblet cellB. another stem cell and a transit amplifying cellC. another stem cell and a goblet cellD. a transit amplifying cell and an enterocyteE. another stem cell and an enterocyte
