The complete question should be:

What is a major distinction between customers who purchase a product because they are brand loyal and those who purchase by inertia?

A) the cost of the product

B) the social risk of the product

C) whether the purchase is made after a compensatory or noncompensatory decision process

D) whether the customers hold a very positive or weak attitude toward the product

whether the customers hold a very positive or weak attitude toward the product

Explanation:

A consumer who buys a product based on inertia is a consumer who buys a product he/she isn't familiar with but is attracted to purchase, therefore no strong link between the consumer and product. While a consumer who purchases a product he/she is loyal to has a very strong connection to that product.

Whether the customers hold a very positive or weak attitude toward the product.

Explanation:

When a customer buys a product by inertia, they are doing it because they are used to doing so, and really pay no attention to the fact that they purchasing that specific product. E.g. when you purchase some convenience products, like toilet paper, milk, spices, etc., you purchase the same brands over and over again not because you are a fan of Charmin and dislike Scott (or vice versa), but because you always buy it.

When someone purchases a good or service because they are loyal to the brand, it means that the product itself is something that is relatively important to them, at least important enough for them to pay attention. Someone who is loyal to a brand will only purchase that specific brand, and if it is not available, will generally not purchase anything. E.g. I like Coke and despise Pepsi, so if there is no Coke, I drink water.
