Answer:
Target Marketing
Explanation:
Candy's Clothes is engaging in target marketing because it is tailoring its marketing strategy (and its products) to a specific, narrowly-defined group of people, which can be thought of as the firm's niche.
This strategy is useful when companies have a clear idea of what demographic group they want to sell. Other firms have products with a broader appeal, and therefore, are better off using other marketing strategies that can reach a larger group of people.
