  Source - Heart
• B. Hormone - Erythropoietin
  Source - Kidney
• C. Hormone - Gastrin
  Source - Gastrointestinal tract
• D. Hormone - Cholecystokinin
  Source - Pancreas

Answer 1

The correct option is D Hormone - Cholecystokinin

Source - Pancreas
Cholecystokinin hormone is secreted by endocrine cells of the gastrointestinal tract. It acts on the pancreas to stimulate the secretion of its enzymes.
Atrial natriuretic factor (ANF) is secreted by the atrial wall of our heart. ANF causes the dilation of the blood vessels which results in decrease in blood pressure and increase in blood flow.
Erythropoietin is a peptide hormone secreted by the juxtaglomerular cells of the kidney. It stimulates the process of RBC(red blood cells) synthesis called erythropoiesis.
Gastrin is secreted by endocrine cells of the gastrointestinal tract. It acts on gastric glands and stimulates the secretion of hydrochloric acid and pepsinogen.
