Answer:
B)The cost of energy for a company can be both a fixed cost and a variable cost.
Explanation:
Energy is a fixed cost because it is an utility that companies have to pay regardless of the level of production; they need energy to function.
Energy is a variable cost because energy is an input to production, and the amount of energy used (and hence its cost) can vary a lot depending on how much output is produced. In the question, ethanol is referenced, which is also a type of variable cost, because it is an energy source that depends on another input (corn), and its used as a substitue for gasoline.
This type of demand is classified as autonomous demand. Autonomous demand does not depend on other products but is due to increase in consumer usage by natural desire. This type of demand is relative to the needs of the consumer.
B and C, are bad feautures. A makes more sense, than D, so A should be your answer.
