Answer: C. does not hold, since the product sold is required for survival, so increasing the price did not affect consumption
Step-by-step explanation:
The law of demand simply stated that when the price of a particular good increases, people will buy less of that product and when there is reduction in the price of the good, consumers will buy more of that particular product.
In the scenario in the question, the law of demand doesn't hold because despite the rise in price, the quantity demanded doesn't change.
Therefore, the correct option is C.
