Consider the following statements with reference to sea waves : 1. The height of waves is determined by wind speed, wind duration, and fetch 2. The energy of a wave is proportional to the square of its height 3. Waves retain most of their energy as they travel across the deep ocean Which of the statements given above is/are correct ?

  1. A. 1 only
  2. B. 1 and 2 only
  3. C. 2 and 3 only
  4. D. 1, 2 and 3
