Answer:
The buyer requirement for "variety" is satisfied through the breadth and depth of products and brands that intermediaries carry.
Step-by-step explanation:
When you go to buy something, you always needs some variety to choose the best thing. In some cases, you get confused what to buy and which is the good thing for you to buy when there is a lot of variety. But when you see variety, you check everything and when you satisfied then you buy the product which you think best for you.
