Answer: E. Walmart has significant bargaining power over its suppliers, which decreases the profitability of the suppliers.
Step-by-step explanation:
Walmart as buyers have significant bargaining power over their suppliers because they are quite large in size and therefore buy in bulk.
As a result of this, they can negotiate prices with suppliers that favor them not the suppliers which will decrease the profitability of the suppliers who would be compelled to sell to Walmart because of how much of their goods Walmart can buy.
