Which mineral salt is dissolved in a major amount in ocean water?

Correct option is C

Sodium chloride, commonly known as table salt, is dissolved in a major amount in ocean water, contributing to its salinity.
This mineral salt is vital for maintaining the osmotic balance of marine organisms and plays a significant role in oceanic ecosystems.
The abundance of sodium chloride in seawater makes it suitable for various industrial and commercial applications.
Calcium Chloride (CaCl₂): Used as a de-icing agent and in dust control, its chemical formula is CaCl₂.
Calcium Carbonate (CaCO₃): Commonly found in antacids and as a calcium supplement; it is also used in industrial applications like cement production, with the chemical formula CaCO₃.
Calcium Sulphate (CaSO₄): Known as gypsum when hydrated, it's used in plaster and drywall; the chemical formula is CaSO₄.
