If managers cannot satisfy, the unusual demand for item A they will lose profit potentials and thus ending up with poor business return. Therefore, these items are reviewed frequently thus; managers maintain a lower lot size and larger safety stock to maintain the unusual demands.

Answer:

Just-in-time (JIT) is a philosophy that supports having the lowest possible inventory. Companies that use JIT, want to avoid the costs incurred in managing inventory. Therefore since the item A,B and C hold the highest to lowest cost (in that order) JIT could help a company to prioritize and reduce the inventory costs of the items holding the greatest amount of cost.
