Which option gives the process of subsistence crisis in the correct sequence?

Harvest failed, grain became scarce, bread became costly.

The governing historical concept is a subsistence crisis: a chain in which poor agricultural production creates scarcity and rising food prices, making ordinary people unable to obtain basic necessities. The correct sequence begins with a failed harvest. Reduced output then produces a shortage of grain, and scarcity pushes the price of bread upward. Expensive bread reduces the purchasing power of workers, especially when wages do not rise equally, and can lead to hunger, unrest, and riots. Option A reverses the price and social consequences, while B describes an improving situation rather than a crisis. Option D lists unrelated or inaccurate developments and does not show the economic chain. Thus option C gives the correct causal order.
