Concept:Base SI units include the kilogram (kg), metre (m), second (s), kelvin (K), ampere (A), mole (mol) and candela (cd). A derived unit is made by combining base units.Explanation:The pascal is the unit of pressure: $1 \text{ Pa} = 1 \text{ N m}^{-2} = 1 \text{ kg m}^{-1} \text{ s}^{-2}$, so it is derived.kg, K and s are base units.Answer:Option C (Pa)
