which one of these quantities are fundamental

Fundamental quantities are those that are independent and cannot be defined in terms of other physical quantities. In the International System of Units (SI), there are seven fundamental quantities: 1. **Length (meter):** The meter is the fundamental unit of length. 2. **Mass (kilogram):** The kilogram is the fundamental unit of mass. 3. **Time (second):** The second is the fundamental unit of time. 4. **Electric Current (ampere):** The ampere is the fundamental unit of electric current. 5. **Temperature (kelvin):** The kelvin is the fundamental unit of temperature. 6. **Amount of Substance (mole):** The mole is the fundamental unit of amount of substance. 7. **Luminous Intensity (candela):** The candela is the fundamental unit of luminous intensity. These seven fundamental quantities serve as the foundation for the measurement system, and all other units can be derived from combinations of these fundamental units.
