Last year, Casey grew fresh vegetables, which she sold at her local farmers market, but this year, Casey did not plant any vegetables and went to work at a bank instead. If Casey's decision to change careers did not affect the price of vegetables at the farmers market, then this suggests that:
A、the demand for vegetables increased this year.;
B、the market for vegetables is perfectly competitive.;
C、the market demand for vegetables is perfectly inelastic.;
D、the demand for vegetables did not change.
