Which of the following most logically completes the passage?

Pecan growers get a high price for their crop when pecans are comparatively scarce, but the price drops sharply when pecans are abundant. Thus, in high-yield years, growers often hold back part of their crop in refrigerated warehouses for one or two years, hoping for higher prices in the future. This year's pecan crop was the smallest in five years. It is nonetheless quite possible that a portion of this year's crop will be held back, since

(A) each of the last two years produced record-breaking pecan yields
(B) the quality of this year's pecan crop is no worse than the quality of the pecan crops of the previous five years
(C) pecan prices have not been subject to sharp fluctuations in recent years
(D) for some pecan growers, this year's crop was no smaller than last year's
(E) the practice of holding back part of one year's crop had not yet become widespread the last time the pecan crop was as small as it was this year

OA A. My doubt is , why not C ? As per the question , producers hoard when production is high to drive up the costs and sell at higher prices when produce is poor.
