Option B, the diver will hear the sound first.

Explanation:

Sound need a medium to travel from one place to another, the medium where atoms are more closely packed together, the better will be speed of sound. That is why sound won't travel in a vacuum because there are no particles to bump together to transmit the vibration.

In air, the particles are generally far from each other so they travel further before they bump into one another. In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air.
