Verified step by step guidance

Step 1: Understand the concept of carbohydrates. Carbohydrates are one of the three macronutrients (along with proteins and fats) and serve as the primary energy source for the body. They are found in foods like grains, fruits, vegetables, and dairy products.

Step 2: Identify the dietary sources listed in the problem. The options provided are: Rice, Salmon, Chicken breast, and Olive oil.

Step 3: Analyze the composition of each food item. Rice is a grain and is rich in carbohydrates, primarily in the form of starch. Salmon and chicken breast are protein-rich foods, while olive oil is primarily composed of fats.

Step 4: Recall that grains, such as rice, are considered primary sources of carbohydrates in the diet. Proteins and fats do not serve as primary carbohydrate sources.

Step 5: Conclude that rice is the correct answer because it is a grain and a primary dietary source of carbohydrates.
