Motivation is about satisfying individual needs by purposive actions. Content theories emphasize these needs and try to predict the type of need in initiating the motivation process. Hierarchy of Needs Theory, X and Y Theory, ERG Theory, Two- Factor Theory and Theory of Needs are called as Content Theories.  Process theories answer the question of “How”. They are based on the process (instead of the need) that the motivated behavior occurs. Thus, each theory explains how the need is activated and turned into behavior. Expectancy, equity and attribution are the significant criteria of these theories. Expectancy Theory, Equity Theory, and Goal-Setting Theory are examples for process theories. The correct answer is Choice C.
