• C. Photosynthesis
• D. Diffusion

Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the key terms provided in the question. 'Fermentation' refers to a metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen. 'Photosynthesis' is the process by which plants convert light energy into chemical energy. 'Diffusion' is the passive movement of molecules from an area of higher concentration to an area of lower concentration. 'Metabolism' encompasses all chemical reactions in the body that maintain life, including the intake and use of food.
2. Step 2: Analyze the question. It asks for the term that describes the process by which the body takes in and uses food. This involves breaking down food into energy and nutrients, which is a key function of metabolism.
3. Step 3: Eliminate incorrect options based on their definitions. 'Fermentation' is not directly related to the body's use of food in a general sense. 'Photosynthesis' is a process specific to plants, not humans. 'Diffusion' is a physical process, not a comprehensive term for food utilization.
4. Step 4: Focus on the correct term, 'Metabolism,' which includes all processes related to the intake, breakdown, and utilization of food for energy and cellular function.
5. Step 5: Conclude that 'Metabolism' is the correct answer, as it accurately describes the process by which the body takes in and uses food.
