Concept:A vector quantity has both magnitude and direction and must obey the rules of vector addition, while a scalar quantity has only magnitude.Explanation:Momentum ($\vec{p}$), force ($\vec{F}$), and displacement ($\vec{s}$) each have a specific direction and combine using vector addition rules.Temperature has magnitude only; it tells how hot or cold something is but has no direction.A quantity with direction but that does not obey vector addition rules is still not a vector.Since temperature cannot be directed and does not obey vector combination rules, it is classified as a scalar.Answer:C. temperature
