On what basis the base quantities of physics are selected?

sks

The base units are:

Kilogram (mass), Meter (Length), Kelvin (Temperature), Mole (Amount of substance), Ampere (Current), Second (Time), Candela (Luminous Intensity)

As we can see most of them can be derived from other quantities. Then why are they called the base quantities & not any other quantity?

No. It is the other way around. They provide the base for deriving other quantities. Hence they are base quantities

Well, the question is on what basis the base quantities are selected as 'base'? Why not any other quantity was selected?

i thought the question was about their nomenclature and how these became the base. if these are the base for others, it follows that their base would be those from which they are derived
Further, as a metric, they provide the base for working out other values currently, who knows-in future, research may hit upon other metrices to become the base
