Answer:
The answer is option (D) Exclusive dealing.
Step-by-step explanation:
Exclusive dealing is a term in competition law that describes when manufacturers enter a contractual agreement with an intermediary (suppliers, retailers or distributors) regarding the sale of only the manufacturer's product through a wholesale sales outlet or retail within a particular region.
This kind of arrangement is mutually beneficial as it 'ties' wholesaler or retailers to purchasing from a manufacturer based on the understanding that no other intermediary in the given area would be appointed to purchase from the manufacturer.
