WHICH statement about gastrin is incorrect?

gastrin stimukates growth of mucosa of small intestine and colon

the most potent releaser of gastrin are pheenyalanine and tryptophan

atropine blocks the vagus mediated release of gastrin

stomach distension stimulates the gastrin secretion.

GAstrin-releasing-peptide or Bombesin is the neuropeptide released at the vagal nerve endings for G (Gastrin )cells. But the Parietal cells are innervated by Ach endings.
