Explanation:

3 and 4 only

Statement 3 is incorrect. In a distinct zone called the halocline, salinity does not necessarily increase sharply. The halocline is actually a zone of rapid change in salinity with depth, but the direction of change can vary depending on the location and oceanographic conditions.

Statement 4 is also incorrect. The statement is not universally true. The salinity in the enclosed Caspian Sea is actually lower compared to the partially closed Mediterranean Sea. The Caspian Sea is a landlocked body of water with limited connection to the global ocean, leading to lower salinity levels compared to the Mediterranean, which has more open connections.

Therefore, the correct option is 3. 3 and 4 only.
