Correct statement is :
  1. (A)An average human being consumes more food than air
  2. (B)An average human being consumes nearly 15 times more air than food✓ Correct
  3. (C)An average human being consumes equal amount of food and air
  4. (D)An average human being consumes 100 times more air than food

Answer: (B)

Solution

Weighing what the body takes in over a day, the intake of air far outweighs that of food. A person breathes many thousands of litres of air each day, amounting by mass to roughly fifteen times the food eaten in the same period. The correct comparison is that an average human consumes about fifteen times more air than food.
