Answer:
B. Food, water, and oxygen.
Step-by-step explanation:
Cells require a supply of essential nutrients to function properly. Food provides the necessary energy and building blocks for cellular processes. Water is essential for maintaining cell structure, facilitating biochemical reactions, and transporting molecules. Oxygen is required for cellular respiration, the process by which cells convert nutrients into energy. Together, food, water, and oxygen support the metabolic activities and survival of cells.
