The correct answer is option 1, which includes yeast, mushroom, and bread mold. In these organisms, food material is broken down outside their body and then absorbed. Let`s understand the other options to see why they are not correct.

Option 2 includes mushroom, amoeba, and green plants. While mushroom and amoeba break down food outside their bodies, green plants perform photosynthesis to produce their own food inside their cells using sunlight, water, and carbon dioxide.

Option 3 consists of caserta, tapeworm, and lice. In these organisms, food is actually broken down inside their bodies by enzymes and then absorbed.

Option 4 contains paramecium, amoeba, and caserta. Similar to option 3, in these organisms, food is also broken down inside their bodies by enzymes and then absorbed.

So, the only group where food material is broken down outside the body and absorbed is option 1, which includes yeast, mushroom, and bread mold.
