Question

the body uses this to carry nutrients and waste. it also helps joints move smoothly.

○ vitamin

○ water

○ fat

● minerals

Explanation:

To determine the correct answer, we analyze the functions described: carrying nutrients and waste, and helping joints move smoothly.

• Vitamins are essential for various metabolic processes but not primarily for transporting nutrients/waste or joint lubrication.
• Water is a key component in the body for transporting nutrients, removing waste (via processes like urine formation), and it also acts as a lubricant in joints (synovial fluid contains water).
• Fat is used for energy storage, insulation, and cell structure, not for nutrient/waste transport or joint movement.
• Minerals have roles in bone health, nerve function, etc., but not the described transport and joint - smoothing functions. So the correct answer is Water.

Answer:

B. Water
