c) Primary and secondary

is the answer

ALL  factors of the question are affect the needs and response of a customer. However, for categorizing the needs and response it is Primary and Secondary

This is a slightly tricky question, a reference group includes individuals or groups that influence our opinions, beliefs, attitudes and behaviors.

If you dig into details, the fact is the response will change if you deal with educated people or uneducated, don't get me wrong here but most of richest people did not come with the high class of education because what they have is a real experience that drove them to their success. Education is important no doubt but theories do not work until you try it for your self. The difference is an educated person will be flexible with certain kind of reports even complex ones however non educated (not necessary the rich guys) needs specific and simple information.

The response will also be effected by culture and society you are in as it will create barrier to limit your option to response like a big super market chain TESCO was successful in UK fastest ever growing business that massively failed in N. Korea until they localized their brand to meet the cultural needs same goes for an individuals considering the level of mutual understanding, compromise and acceptability that varies from individual  to individual resulting in a profound personality that will create variation in responses some at logical extend and some will be driven with emotions to influence and create the connection.

But these are few factors to be considered at individual response both when interacting directly or indirectly i.e. Primary and Secondary reference groups.
