Final answer:
There is no universal rule for garnishing platters with three specific items; it depends on the dish and cuisine. For a pulled pork plate like the one from North Carolina, coleslaw, beans, and hush puppies are common garnishes. Options provided represent suitable garnishes for various types of platters.
Step-by-step explanation:
When garnishing platters, there isn't a one-size-fits-all rule for what three things should be used, as garnishes often vary depending on the dish and the cultural or regional cuisine. However, figure 3-6 from our reference indicates that in North Carolina, a pulled pork platter is commonly served with red coleslaw flavored with vinegar, beans, and hush puppies. This reflects that traditional garnishes for barbecue dishes in this region include items that complement the main dish both in taste and texture.
The options provided (A) Coleslaw, pickles, and cornbread; (B) Mashed potatoes, gravy, and green beans; (C) French fries, ketchup, and a lemon wedge; (D) Rice, beans, and a fruit salad reflect a variety of potential garnishes that could be appropriate for different types of platters. Without more specific context about what type of platter is being prepared, it's difficult to say which set of garnishes would be suitable.
