Answer:
The correct answer will be option-C
Step-by-step explanation:
The pancreas is a small pear-shaped gland present in the abdomen and surrounded by the stomach. The pancreas acts as both endocrine (secretes glucagon and insulin hormones) and exocrine (secretes digestive enzymes).
In the given question, the pancreatic part removed from the rat results in the loss of appetite as when insulin is not produced in the body results in uncontrolled sugar levels in the body. This leads to the loss of water from the body to the urine and as a result, the loss of appetite is observed.
Since the endocrine portion controls the insulin production therefore, option-endocrine is the correct answer.
