What may occur in one account concerning selling price?

The correct answer indicates that the selling price may lag a quarter. This is significant because it reflects the operational dynamics of how pricing strategies are implemented within the context of 340B program operations.

When a selling price lags a quarter, it means that any adjustments or changes to pricing based on market trends, manufacturer pricing, or other economic factors may not be immediately reflected in the pricing structure. This time lag allows for price stabilization and can help organizations manage their financial operations more effectively by not making hasty or reactive price changes each quarter.

In the context of the 340B program, understanding market conditions and timing can be critical for managing costs and compliance efficiently. Organizations might analyze market data and make adjustments accordingly, but these adjustments can take time to implement and be reflected in the selling prices.

The other options imply more immediate or rigid pricing strategies, which may not allow for the necessary flexibility to adapt to market changes or operational considerations. Thus, the notion of lagging pricing provides a more realistic and practical approach to managing selling prices within the 340B program framework.
