Solution

The correct option is A high speed
$P = ρ g h$
At deep sea, pressure is very high and fishes there are evolved to sustain that. So when they are brought to the surface, their inner blood pressure is too high compared to pressure outside, so it bursts their body.

Option B is correct.

Why does the body of a deep sea fish burst on bringing her above the sea level?

Q. When a sea diver goes very deep he has to breathe on compressed air at high pressure. After some time, he loses his strength to work and feel drowsy. This is because of:

A deep sea diver jumps into a sea in search of a ship wreck located below the sea level. The suit of the diver helps him maintain his body pressure at the normal atmospheric pressure. This suit can sustain a maximum pressure of 6 atm. The density of sea water is 1.03 × 10³ kg m⁻³

With reference to sea pressure, the diver can safely reach the maximum depth of about

g = 9.8 m/s²& 1atm = 1.01 × 10⁵Pa
