Solution

The correct option is A True
A vector is a quantity that has magnitude and acts in a certain direction.
Scalar describes a quantity that has magnitude but no definite direction.
So scalar quantities can be added using the arithmetic rule because they have no direction.
Hence, the statement is true.
