Answer:
A) Make the core brand as distinctive and differentiated as possible.
Step-by-step explanation:
Comparative advantage in economics is the ability of an individual or country to produce a specific good or service at a lower opportunity cost better than another individual or country.
The company advantage gives a country a stronger sales margin than their competitors as they are able to sell their specific products or render their peculiar services at a lower opportunity cost.
In this scenario, Galaxy chocolate has successfully competed with Cadbury by positioning itself as "your partner in chocolate indulgence" and featuring smoother product shapes, more refined taste, and sleeker packaging, which represents making the core brand as distinctive and differentiated as possible.
Galaxy chocolate worked on its brand by developing strategies that made its brand unique, distinctive and different from that of Cadbury, thereby giving them a competitive advantage or edge.
