Answer:
#3 digested into simple sugars
Step-by-step explanation:
Starch is a carbohydrate, but specifically a polysaccharide. Unlike fats they cant be broken down so #2 is not correct for that reason. Since polysaccharides are a polymer of complex sugars they can be broken down to simple sugars in order for it to enter cells because the cell needs to transport the molecules in small portions not big. That is when the different types of transport comes in. :)
