Which of the following schools of Human Geography developed as a result of discontentment with the quantitative revolution and its dehumanised manner of doing geography?

All of the above.

The correct answer is Option 4: All of the above.

The quantitative revolution in geography (1950s–60s) emphasized statistical and mathematical methods to make geography more scientific. However, this led to criticism that it was too abstract, mechanical, and ignored the human experience. Discontentment with the quantitative revolution and its dehumanised manner of doing geography led to the emergence of three new schools of thought of human geography in the 1970s i.e. Humanistic, Radical and behavioural. Human geography was made more relevant to the socio-political reality by the emergence of these schools of thought.
