Let’s analyze each of the statements to identify the wrong ones:

A. Erythropoietin is produced by juxtaglomerular cells of the kidney

This statement is incorrect. Erythropoietin is primarily produced by the interstitial fibroblasts in the kidney, not by the juxtaglomerular cells.

B. Leydig cells produce Androgens

This statement is correct. Leydig cells in the testes produce androgens, such as testosterone.

C. Atrial Natriuretic factor, a peptide hormone, is secreted by the seminiferous tubules of the testes

This statement is incorrect. Atrial Natriuretic factor (ANF) is secreted by the cardiac atria, not by the seminiferous tubules of the testes.

D. Cholecystokinin is produced by the gastrointestinal tract

This statement is correct. Cholecystokinin is a hormone produced by the cells in the mucosal lining of the small intestine.

E. Gastrin acts on the intestinal wall and helps in the production of pepsinogen

This statement is incorrect. Gastrin primarily acts on the stomach lining (gastric mucosa) to stimulate the secretion of gastric acid and pepsinogen, not the intestinal wall.

Based on this analysis, the wrong statements are A, C, and E. Therefore, the most appropriate answer from the given options is:

Option C

C and E only
