The correct option is C Parietal cells

Stomach has a membrane called mucosa or mucous membrane. This membrane has 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 $B_{12}$.
