D. Oesophagus: The esophagus transports food but does not produce enzymes like trypsin.

Correct Answer is A

Explanation

A. Proximal convoluted tubule: The proximal convoluted tubule is the main site of creatinine secretion as well as the reabsorption of nutrients and water.

C. Collecting duct: This part primarily deals with water and electrolyte balance but is not the main site for creatinine secretion.

D. Loop of Henle: This structure plays a key role in water and sodium balance but does not play a significant role in creatinine secretion.
