Which of the following pairs correctly identifies one example of a visible fat and one example of a hidden fat?

Butter on toast (visible) and oil baked into pastry dough (hidden)

Visible fat: fat streaks in a steak; Hidden fat: clear cooking oil poured over vegetables

Visible fat: mayonnaise stirred into potato salad when prepared at home so it can be seen; Hidden fat: bacon strips laid on top of a sandwich such that grease and fat are visually obvious

Avocado flesh (visible) and olive oil drizzled on salad (hidden because liquid oils are less obvious and more likely to be overlooked by consumers who inspect appearance only)
