* SI Base Units: The International System of Units (SI) has seven base units:
* Meter (m): Unit of length.
* Kilogram (kg): Unit of mass.
* Second (s): Unit of time.
* Ampere (A): Unit of electric current.
* Kelvin (K): Unit of thermodynamic temperature.
* Mole (mol): Unit of amount of substance.
* Candela (cd): Unit of luminous intensity.
* Joule (J): The joule is a derived unit, representing energy. It is defined as 1 kg⋅m²/s² (kilogram meter squared per second squared).
* Inch (in): The inch is a unit of length in the imperial system, not the SI system.
* Meter (m): As mentioned, this is an SI base unit for length.
In summary: The only SI base unit in your options is the meter (m).
