To solve this problem, we need to identify the fruit in which both the placenta and pericarp are edible portions.$\newline$Let's analyze each option:$\newline \bullet$Option 1: Apple - In apples, the edible part is mainly the fleshy receptacle, not the placenta or pericarp.$\newline \bullet$Option 2: Banana - In bananas, the edible part is the fleshy mesocarp, not the placenta or pericarp.$\newline \bullet$Option 3: Tomato - In tomatoes, both the pericarp and the placenta are edible. The pericarp forms the outer fleshy part, while the placenta contains the seeds.$\newline \bullet$Option 4: Potato - Potatoes are tubers, and the edible part is the modified stem, not the placenta or pericarp.$\newline$Therefore, the correct answer is Option 3: Tomato, where both the placenta and pericarp are edible portions.
