All the following are factors that influence consumer buying EXCEPT:

The correct answer highlights that a store's change in ownership typically does not directly influence consumer buying decisions compared to the other factors listed. Factors such as the number of people in the family, consumer knowledge and information, and the health of family members play a more significant role in influencing purchasing behavior.

The number of people in a household can affect buying patterns based on family needs, preferences, and budget constraints. For instance, larger families might prioritize bulk buying, while smaller families may focus on convenience. Consumer knowledge and information directly impact decision-making, as well-informed consumers are more likely to make choices that align with their needs and preferences. Health of family members can also significantly impact purchases, as it dictates dietary needs and the choice of products, whether for specific health conditions or general wellness.

On the contrary, while a change in store ownership could potentially affect some aspects of a shopping experience, such as management style or product selection, it usually has a less immediate or pronounced effect on direct consumer buying behavior compared to the personal factors tied to family dynamics and individual consumer awareness.
