b) False
Explanation:
This statement is false one because while making a decision there are numerous factors involved, for example:
Initiator: The person who after processing some information about a product, watching an ad etc, initiates the task of buying it.
Influencer: Person who influence the initiator further processing.
Decider: Person who decides that the particular products should be bought.
Purchaser: Person who actually go to the market and purchase that product.
User: Person who actually use that product.
In above all of the described roles, it could be one single person who perform all the tasks, or it could be 2 to 5 different persons involved and each one performing the separate role. So, there are 5 roles involved in an actual buying process, here family role comes that it is obvious that much roles are involved, any single role can be performed by any of his or her family member, therefore, family influence is there in a purchase decision, somehow or other.
