Answer:
its B) Thermohaline currents Sorry if its wrong but im sure this could be it
Explanation:These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.
Thermohaline currents deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses
What is thermohaline currents?
Thermohaline currents is also known as 'the ocean conveyor belt' or 'the global conveyor belt'. It is a part of the large scale ocean circulations.
As the name thermohaline suggested that, 'thermo' means heat and 'haline' refers to the salt content. So, when there is a great difference in the temperature and the salt content deep sea currents occur.
Hence option (2) is correct i.e. thermohaline currents occur due to temperature and salinity difference.
