The Zara Experience Involves a Regular Supply of New Stocks

The Zara experience involves a regular supply of new stocks on the shelves, because of which customers tend to visit Zara's stores more often than they visit other retailers' stores. However, such a policy will become more expensive to maintain if:

A) star designers demand a higher fee for its designs.
B) PDAs are not used.
C) fuel costs rise.
D) Zara's horizontal integration fails.
E) Zara outsources its production process.
