Analyze the biological role of proteins

Proteins are essential macromolecules in the human body. Their primary physiological role is to serve as structural components, building and repairing body tissues such as muscles, skin, and organs. While they can be used for energy under extreme starvation, carbohydrates and lipids serve as the primary sources of energy. Therefore, the correct role is "Builds and repairs body tissues".

Identify dietary sources of protein

To obtain proteins, humans must consume protein-rich foods. Fish is an excellent dietary source of complete protein, containing all essential amino acids. In contrast, vitamins are micronutrients that do not contain proteins. Thus, the correct source is "Fish".

Evaluate the given options

We look for the row that combines the correct role ("Builds and repairs body tissues") and the correct source ("Fish"):

• Row 1: Primary source of energy / Fish (Incorrect role)
• Row 2: Primary source of energy / Vitamins (Incorrect role and source)
• Row 3: Builds and repairs body tissues / Fish (Correct role and source)
• Row 4: Builds and repairs body tissues / Vitamins (Incorrect source)

</reasoning>

<answer>
<mcq-option>(A) Primary source of energy | Fish</mcq-option>
<mcq-option>(B) Primary source of energy | Vitamins</mcq-option>
<mcq-correct>(C) Builds and repairs body tissues | Fish</mcq-correct>
<mcq-option>(D) Builds and repairs body tissues | Vitamins</mcq-option>
