Verified step by step guidance1
Understand that the International System of Units (SI) defines standard units for various physical quantities, including mass.
Recall that the SI base unit for mass is the kilogram, which is symbolized as kg.
Recognize that the gram is a derived unit related to the kilogram, where 1 kilogram equals 1000 grams, but the gram itself is not the base SI unit.
Note that pound and ounce are units of mass used primarily in the imperial system, not the SI system.
Conclude that among the options given, the kilogram is the correct SI unit for mass.
