Belmont Industries submitted a proposal to Arkland's head provincial administrator, recommending the company's thin salt-layer spray, which can be applied to city streets to make deicing and snow-removal considerably more efficient. However, the provincial administrator is likely to recommend that Belmont's spray not be implemented in its road-maintenance program because the spray would add to the already strained provincial seasonal road-maintenance budget. Which one of the following is assumed by Arkland's provincial administrator?
A. Belmont's salt-layer spray does not provide any benefits other than for deicing and snow-removal.
B. Adding agents other than Belmont's salt-layer spray are likely to cost the province even more.
C. Arkland's winters typically stay within a narrow temperature range from winter to winter, but snowfall can vary considerably.
D. Funds saved from implementation of Belmont's salt-layer spray would not exceed the cost associated with the spray's implementation.
E. Arkland's current deicing and snow-removal program does not already utilize the least expensive of available alternatives.
