Answer 1

The correct option is C

2 and 3 only
Explanation:

Statement 1 is correct: The Salinity of water in the surface layer of oceans depends mainly on evaporation and precipitation.

Statement 2 is incorrect: The average salinity of the Indian Ocean is 35 o/oo. The low salinity trend is observed in the Bay of Bengal due to the influx of river water. On the contrary, the Arabian Sea shows higher salinity due to high evaporation and low influx of freshwater.

Statement 3 is incorrect: The North Sea, in spite of its location in higher latitudes, records higher salinity due to more saline water brought by the North Atlantic Drift. It is a warm ocean current and an extension of the Gulf Stream. It is characterized by warm temperature and high salinity.
