Answer 2

Answer:

Fundamental units- A fundamental (or basic) unit is that which is independent of any other unit or which can neither be changed nor can be related to any other fundamental unit. Eg- The units of mass, length, time, temperature, current and amount of substance are independent of each other as they are of different nature. They cannot be obtained from the unit of any other quantity. These are the fundamental units.
