Answer:
The increase in ads for prepared trays of food to be served at these functions is directly related to usage/occasion segmentation.
Explanation:
In marketing, occasion segmentation refers to the targeting of consumers according to the occasion or usage for a product. That is, the market understands consumers tend to purchase a certain product for a certain event or during a specific time of the year. That would explain the ads for prepared trays of food during November and December, a period when people tend to have family and friends over to celebrate Thanksgiving and Christmas.
