Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.

Salinity of Sea Water
Definition: Salinity is the measure of the amount of dissolved salt in seawater.
Average Salinity: The average salinity of seawater is 3.5%, which means that for every 1 liter (1000 mL) of seawater, there are 35 grams of salt.
Factors affecting Salinity: The salinity of seawater can be affected by several factors such as:
Importance of Salinity: The salinity of seawater is an important factor in determining the ocean's density, which affects ocean currents and the distribution of marine life. It also affects the freezing point of seawater, which can impact the formation of sea ice.
Therefore, the correct answer to the question is option B) 3.5%, as it represents the average salinity of seawater.

Factors affecting Salinity: The salinity of seawater can be affected by several factors such as:
- Evaporation: When seawater evaporates, the amount of salt in the remaining water increases, leading to an increase in salinity.
- Precipitation: When it rains, freshwater mixes with seawater, diluting the salt concentration and reducing salinity.
- Ice formation: When water freezes, the salt is left behind, leading to an increase in salinity.
- Flow of freshwater into the sea: The flow of freshwater from rivers into the sea can dilute the salt concentration and reduce salinity.

The average salinity is about 35 parts per thousand. Stated in another way, about 3.5 percent of the weight of seawater comes from the dissolved salts.
