Which of the following statements is/are true/false about speed of sound in different media at 25°C? 

Statement :
A. In water (sea), the speed of sound is 1531 $$\frac{m}{s}$$.
B. In water (distilled), the speed of sound is 1498 $$\frac{m}{s}$$.

A. In water (sea), the speed of sound is 1531 $$\frac{m}{s}$$.
B. In water (distilled), the speed of sound is 1498 $$\frac{m}{s}$$.

Both statements are true.

Speed of sound in any medium depends on the density of the medium or simply how close the particles are packed in that medium. As sound wave is propagated due to vibration of particles, closer the particles / denser the particles faster the speed of sound. Since, density of sea water is more than distilled water due to the presence of salt in it speed of sound is more in seawater than distilled water.

Option C is correct.
