Solution

The correct option is A Pancreas
a) Lungs help in excretion of excess carbon dioxide from the body through the process known as respiration.
b) Pancreas functions to secrete hormones insulin and glucagon and digestive enzymes. Hence it has digestive and endocrine functions but not excretory functions.
c) Liver breaks down substances which are toxic or are too large to filter through the kidney into smaller and lesser toxic molecules and hence is involved in excretion.
d) Excess water and salts are removed from the body as sweat through the skin. Thus, it is involved in excretion.
So, the correct answer is 'Pancreas'.
