Step 1: Understand the categories. Food is the broadest category. Vegetables are a subset of Food. Potatoes are a subset of Vegetables.
Step 2: The Venn diagram should show Food as the largest circle. Vegetables inside Food. Potatoes inside Vegetables. This represents: Potatoes ⊂ Vegetables ⊂ Food.
Step 3: From the options in image 47.png, Option 2 shows three concentric circles (Food largest, Vegetables inside, Potatoes innermost). Therefore, option (B) is correct.
