Final answer:
Harvest pricing is commonly used in the decline stage of the product life cycle to maximize short-term profits. The four pillars of food security are availability, access, utilization, and stability; transformation is not one of them.
Step-by-step explanation:
The strategy of harvest pricing is typically employed in the decline stage of the product life cycle. This approach involves reducing investment in a product, maximizing short-term profits and revenue from it before discontinuing its sale. When a product is in the decline phase, the market for it may be shrinking, and companies often try to squeeze out the last bit of profit before ultimately phasing out the product.
To address the review question, the four pillars of food security are availability, access, utilization, and stability. The option that is not one of these pillars is Transformation, which does not represent a recognized pillar of food security.
