Explanation:

The small intestine is a key organ for chemical digestion and absorption. Nutrients spend approximately 4 hours in the small intestine for these processes to occur. 12 and 24 hours are too long for the normal transit time in the small intestine for digestion and absorption. 2 hours is too short as the processes are more complex and take longer.
