Please help, will give brainliest !! Explain the role of density in the movement of deep currents.

A. Cold, high salinity (salty) deep current water is less dense than warm, low salinity
surface current water. As warm water sinks, cold water will move in to take its
place, creating a circular movement called a convection current.

B. Cold, high (salinity) deep current water is more dense than warm, low salinity
surface current water. As warm water rises, cold water will move in to take its
place, creating a circular movement called a convection current.

C. Warm, high salinity (salty) deep current water is more dense than warm, low
salinity surface current water. As warm water sinks, cold water will move in to
take its place, creating a circular movement called a convection current.

D. Warm, high salinity (salty) deep current water is less dense than warm, low
salinity surface current water. As warm water sinks, cold water will move in to
take its place, creating a circular movement called a convection current.
