The correct answer is <em>C) "personal appeals"</em>.
When a speaker is searching for support in an audience it is very effective to refer to the friendship and loyalty that this audience has had towards the speaker until that moment and ask once again for their support regarding the upcoming decision-making process. This is a technique which political candidates use quite often during political meetings in the days prior to the election day. Proposals and the appliance of techniques such as exchange are no longer effective with such a tight deadline, leaving the personal appeal as the best way to reach an audience's emotions and get the necessary buy-in.
In a market economy the production is determined not by someone's decision <em>(which can be wrong, and a wrong decision is the reason why there there are unwanted goods or a lack of wanted goods) </em>but it is regulated by the supply and demand: if there is a need for a good, it will be produced, and if there is no need for something, its production will halt and there will not be an unwanted storage.
In short, in a market economy, the economy itself regulates this.
