I go to the grocery store daily and buy same brand of bread, butter and milk , Which buying behaviour am I displaying?

First choice

 

 

[A] Routine response behaviour,

Its basically habitual or routine buying behavior but it involves "Limited decision making" because you are buying the same products & brands daily without changing anything thus you don't get involved much in the buying process. Thanx for the invitation

Thank you for invocation.

I tend to answer A....

Displaying routine response behavior as the buyer is not very involved and does not think extensively about the brands substitutes.
