The correct answer is D) the value of resources.
Based on economics, the most influential in making the decision would be the value of the resources.
School band members need to raise money for new uniforms. Some members want to sell energy drinks at a football game, but others want to organize a car wash in the school parking lot.
The School band has to take into consideration the value of its resources. If they have appropriate resources to organize a car wash, they can opt for these options. It probably is going to require more resources than to sell drinks in the game, but the possibility to collect more money is far high.
The other options of the question were a) the labor needed, b) the consumer appeal, and c) the capital needed.
