Final answer:
The supermarket's decision to start a new home delivery service relates to the Place element of the marketing mix.
Step-by-step explanation:
The supermarket's decision to start a new home delivery service relates to the Place element of the marketing mix.
The marketing mix consists of four elements: Product, Price, Place, and Promotion. Place refers to the location where the product is made available to the target customers.
In this case, the supermarket is expanding its service by offering home delivery. This means that the product (groceries) will now be delivered directly to the customers' homes, making it more convenient for them to access the product.
By adding home delivery as a new distribution channel, the supermarket is using the Place element of the marketing mix to meet the needs of its customers and increase accessibility to its product.
