Solution

The correct option is A True
Valency
Valency of the elements varies from 1 to 4.
If valency = 1,than element is known as monovalent
If valency = 2 then the element is known as bivalent
If valency = 3 then the element is known as trivalent
If valency = 4 then the element is known as tetravalent.
If valency = 0, then the element is chemically stable and non-reactive in nature.
Therefore the given statement is true.
