A broad differentiation strategy would work best for which of these companies?

a. American Giant, because it possesses the capability to incorporate attractive or upscale attributes at a lower cost than rivals

b. Canada Goose, because using small-scale production or custom-made products, it focuses on product features and attributes that appeal specifically to niche members

c. Clincas del Azcar, because it is able to use technology to lower its costs significantly by limiting its customer base to a well-defined buyer segment

d. Prada, because it can command a high price premium for its high-fashion designs.

e. Vanguard, because the products of rival sellers are essentially identical and are readily available from several sellers
