Answer: the options are added below:

A. market forces would quickly direct an economy back to full employment.

B. lower wages would cause the central bank to reduce the money supply and thereby prolong the recession.

C. lower wages would stimulate inflation and thereby prolong the recession.

D. powerful trade unions and large corporations made wages highly inflexible.

The correct option is D.

Explanation: A Trade Union is also known as a labour union and it is an association of workers in a particular trade, industry, or company that is created for the aim of negotiating improvements in wages and salaries, benefits, better working conditions, or social and political status through collective bargaining.

The view of Keynes is that the trade unions that have become powerful have, in conjunction with large corporations, made wages highly inflexible.

What this means is that they always make sure that there will be no supply of labor if the wages are low, therefore Keynes is of the view that lowering wages will not direct a recessionary economy back to full employment, rather, increasing the wages will ensure that the trade unions and large corporations supply labor and therefore increase employment.
