A). Demand, supply, demand.

Explanation:

The process is categorized as 'demand-constrained' in a situation when the supply surpasses the demand and flow rate remains equal to the demand rate. The flow rate and demand rate are equal as there is excess supply in the market and thus, the alteration in demand curve would only affect/influence the flow rate. In such a situation, supply of goods become excessive that leads to fall in prices of products and involuntary employment that may head the economy towards deflation. Therefore, option A is the correct answer.
