Final answer:
Brand loyalty is when customers are reluctant to switch away from their favorite brand of a particular product.
Step-by-step explanation:
When customers are reluctant to switch away from purchasing their favorite brand of a particular product, this is known as Brand loyalty. Brand loyalty refers to the loyalty and attachment that customers have towards a particular brand, which makes them resistant to switching to other brands even when there are alternatives available.
For example, if a customer has been using a particular laundry detergent brand for a long time and is satisfied with its performance, they may be hesitant to switch to a new brand, even if it is advertised as being better than their current brand.
