The correct option is D All of the above
Price mechanism
refers to the mechanism where price directs the flow of goods and services in
the market as it directs the supply by the production sector i.e supply will
increase if price increases and vice-versa and the demand sector i.e demand
will increase if price decreases and vice-versa. Therefore for price mechanism to operate smoothly, government intervention needs to be avoided with free flow of all the resources required for the production of the demanded commodities.
