A sudden drought sharply reduces the wheat harvest in a major exporting country. In the short run, the price of wheat is most likely to rise by a large amount relative to the fall in supply because:

Wheat prices jump because short-run supply and demand are both inelastic. Producers cannot quickly replace a lost harvest and consumers cannot easily substitute, so a modest supply fall requires a large price rise to clear the market.

  1. Awheat storage costs are always negative
  2. Bsupply and demand for wheat are both relatively inelastic in the short runCorrect
  3. Cproducers can immediately plant additional crops

Explanation

Crop supply cannot adjust quickly within a growing season and consumers have few substitutes for staples, so both curves are inelastic and a supply shock causes a large price move. Planting more cannot offset a lost harvest immediately, and storage costs are positive.
