C Correct answer
Explanation

A halocline is a cline caused by a strong, vertical salinity gradient within a body of water. As salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical stratification. Increasing salinity by one kg/m3 results in an increase of seawater density of around 0.7 kg/m3.
