In which circumstance are competitive pressures associated with the bargaining power of buyers not relatively strong?

When buyer demand is growing rapidly, competitive pressures associated with the bargaining power of buyers tend to be weakened. This is largely because strong demand can shift the balance of power from buyers to sellers. In situations where demand is high, companies may find it easier to raise prices or maintain higher margins, as buyers are more willing to purchase the product due to its perceived value or necessity.

In contrast, when buyers are well informed, they have the tools to negotiate more effectively, increasing their bargaining power. If buyers pose a significant threat to integrate backward, they can exert pressure on prices and terms, further enhancing their bargaining strength. Lastly, when there are few substitutes available, buyers have limited options, which means they are less likely to negotiate aggressively or to seek alternative suppliers. Thus, the context of rapidly growing buyer demand inherently diminishes competitive pressures related to buyer bargaining power, making this the correct answer.
