The answer is the second one: Parietal cell.

Explanation for each option:

  • Enteroendocrine cell: These cells secrete hormones into the bloodstream, not hydrochloric acid.
  • Parietal cell: These cells are responsible for secreting hydrochloric acid (HCl) in the stomach, which aids in digestion.
  • Mucous neck cell: These cells secrete mucus to protect the stomach lining, not hydrochloric acid.
  • Chief cell: These cells secrete pepsinogen, an inactive enzyme precursor, not hydrochloric acid.

In summary, the parietal cell is the correct answer as it is the cell in the stomach that secretes hydrochloric acid.
