Answer: Option (c) is correct.
Step-by-step explanation:
Correct option: The desire and the ability to pay for the item.
A person demand for a good, if he really wants to buy that good and has the willingness to pay for that good. He doesn't demand for a good if there is no desire to have it and when a good is not affordable for him.
So, demand for a particular good is largely dependent upon the tastes and preferences and money income of a consumer.
