Answer:
If consumers who ate meat regularly in the past shifts to other substitute diets,then lower demand for meat could pull the meat price at least in the short term.Hence,the correct option could be (C) in this case.
Step-by-step explanation:
Initially based on the basic demand and supply theory in Microeconomics,the excessive demand for corn as a livestock feed would increase the global corn price which along with less meat suppliers would be sequentially reflected in higher meat prices.Now,the higher price of corn as a raw material for livestock maintenance would raise the final price of meat in the market but to lower the prices at the same time,some demand side adjustment/s need/s to be made to restore the meat price to its previous point or position.Therefore,if the consumers switch to substitute diets for meat,the demand for meat decreases in the near future or considerably short period and the expected hike in meat price can be prevented or it can possibly decrease.Therefore,based on the demand and supply model,in this case,demand side adjustments in the market can expectedly contain the meat prices and pull it down in the short run.
