Answer:
C. Keynes stressed the demand side of an economy while classical economists stressed the supply side of the economy.
Step-by-step explanation:
The significant distinction between the classical and Keynesian view of the economy is that Keynes lays emphasis on the demand side of the economy while classical economists focus more on demand-oriented evaluation and correction of imbalances in the economy.
Classical theorists assert that 'supply has the ability to produce its own demand.' It says that 'the production will generate sufficient income to purchase all the output produced in the economy' while Keynes claims that demand is the key driving force that drives the economy. Thus, the former relied on monetary policy while the latter on fiscal policy.
