> c. is the correct answer. Howard Gardner's theory of Multiple Intelligences is a valid, reliable model that expands the construct of intelligence.
The theory of multiple intelligences proposed by Harvard psychologist Howard Gardner suggests that all people have different kinds of intelligence (eight to nine intelligences) and that traditional psychometric views of intelligence are limited. This theory enjoys considerable popularity with educators. Gardner proposed in his book "Frames of Mind: The Theory of Multiple Intelligences" that people do not have just an intellectual capacity, but have many kinds of intelligence.
