SI units for Base Physical Quantities of length, mass and current area...
The SI units for the base physical quantities of length, mass, and current are as follows:
**Length: Meter (m)**
- The meter is the SI unit for measuring length.
- It is defined as the distance traveled by light in a vacuum during a specific time interval.
- The meter is widely used for measuring distances, heights, widths, and other dimensions.
**Mass: Kilogram (kg)**
- The kilogram is the SI unit for measuring mass.
- It is defined as the mass of the International Prototype of the Kilogram (IPK), which is a platinum-iridium cylinder stored at the International Bureau of Weights and Measures (BIPM) in France.
- The kilogram is used to measure the amount of matter in an object.
**Current: Ampere (A)**
- The ampere is the SI unit for measuring electric current.
- It is defined as the constant current that, if maintained in two straight parallel conductors of infinite length and negligible cross-section, placed one meter apart in a vacuum, would produce a force between these conductors of exactly 2 x 10^-7 newtons per meter of length.
- The ampere is used to measure the flow of electric charge.
Therefore, the correct answer is option A: Meter, kilogram, ampere. These choices represent the SI units for the base physical quantities of length, mass, and current, respectively.

SI units for Base Physical Quantities of length, mass and current area...
Mass in kg so kilogram is the SI unit of mass m current always in A so amphere is the SI of currentLength always in m so meter is the SI unit of length
