  • A. Neither A nor B is correct.
  • B. Both A and B are correct.
  • C. Only B is correct.
  • D. Only A is correct.
Correct Answer: Option A - At 25 °C the speed of sound in seawater is 1531 m / s and in water (distilled), speed of sound is 1498 m / s. Hence, Neither A and B are correct.
A. At 25 °C the speed of sound in seawater is 1531 m / s and in water (distilled), speed of sound is 1498 m / s. Hence, Neither A and B are correct.
