(a) Interpretation: The term SI base units need to be defined. Concept introduction: The term is defined as a phrase or word to explain a concept or thing. For example: for the description “anything that occupies space and have mass” is termed as matter. Symbol is a character used to represent a function, object or process. For example: the SI unit of mass is kilograms and its symbol is kg.
