-  ‘most of the people’ in place of ‘most of people’ because before plural noun used after ‘most of’ article must be used.

The correct phrase is "most people," not "most of people." "Most people" is a common English phrase used to refer to a majority or a large group of individuals. "Most of people" is grammatically incorrect because "of" should not be used with "most" in this context.
