Final answer:
The correct answer to the functions of the large intestine is 'D. Both b and c,' which includes the absorption of some water and minerals, and the secretion of mucus.
Step-by-step explanation:
The function of the large intestine involves the absorption of water and the removal of waste. Specifically, the options provided to the question, 'Which of the following is/are the function(s) of large intestine?' with the correct answer being D. Both b and c. This means the large intestine is responsible for the absorption of some water and minerals (B) and the secretion of mucus (C).
The large intestine does consist of the cecum, the colon, and the rectum, where it performs critical functions in water reabsorption, mineral salt extraction, and waste storage. Goblet cells within the mucosa secrete mucus that facilitates the smooth passage of feces, making the presence of mucus a key component of the large intestine's function.
