Let's assume the distance between the iceberg and the ship be 'd' meters.

We know that the speed of sound in water is 1 530 m/s and the speed of sound in air at -5°C is approximately 331 m/s.

The time difference between the person hearing the sound in water and air is 4.0 s.

Therefore, we can write:
d/1530 - d/331 = 4

Multiplying through by 1530*331, we get:
d*331 - d*1530 = 4*1530*331
1199d = 2 018 640
d = 1 682.6 ≈ 1 700 m

Hence, the best answer choice is B) 1 700 m.
