Answer: a. Brands enhance loyalty.
Step-by-step explanation:
Brands enhance loyalty because people are more likely to identify with a symbol than with something that has a general identity. When a company has a brand therefore, it will enhance the loyalty of its consumers as they look to identify with that brand.
Take Adidas for instance, the three stripes logo is so iconic that people can sometimes have entire wardrobes of Adidas apparel to show those three stripes off and show that they identify with it. This is the benefit that Nancy stands to gain with branding.
