Step-by-step explanation:
The question refers to the number of eggs that constitute a serving in the 'Meat and Alternatives' food category. According to dietary guidelines, a typical serving size of this category can vary depending on the specific type of meat or alternative used. For eggs, a standard serving size is often considered to be about 1 large egg. Taking this into account, and looking at the options provided (a) 2 eggs, (b) 4 eggs, (c) 1 egg, and (d) 3 eggs, the correct answer that aligns with general dietary recommendations would be (c) 1 egg.
An example given in the reference suggests that for making pancakes, 2 cups of mix require one egg. Therefore, if you were to scale up to 9 cups of mix, you would need approximately 4½ eggs. This illustrates a proportional relationship between ingredients in recipes and can provide some insight into standard serving sizes.
