Solution

The correct option is D Parietal cells
Gastric glands have three types of cells:

1. Mucus neck cells: They secrete mucus.
2. Peptic or chief cells: They secrete pepsinogen.
3. Parietal or oxyntic cells: They secrete HCl and intrinsic factors. The intrinsic factors are essential for the absorption of vitamin B12. The process of red blood cell formation is called as “erythropoiesis'. Vitamin B12 helps the body make healthy red blood cells and helps keep nerve cells healthy.

Vitamin B12 (Cobalamin) is a water-soluble vitamin that is derived from animal products such as red meat, dairy, and eggs. Intrinsic factor is a glycoprotein that is produced by parietal cells in the stomach and is necessary for the absorption of B12.

The intestinal mucosal epithelium has goblet cells which secrete mucus.
