Which situation would be the strongest explanation of a subsistence crisis?

Grain shortage together with costly bread and low wages

Option A gives the strongest explanation of a subsistence crisis because it combines shortage, rising prices and weak purchasing power. A poor harvest could reduce the supply of grain, while scarcity pushed bread prices upward. If wages remained low or employment declined, ordinary families could no longer buy enough food to meet basic needs. This was a crisis of subsistence, meaning a threat to minimum survival rather than merely a complaint about luxury or political symbolism. Options B, C and D describe social or institutional features of the Old Regime, but none directly explains why people could not afford essential food. The governing concept is the interaction between food supply, prices, income and household survival.
