Answer: The good is necessary for survival (e.g., a life-saving drug)
Explanation:
INELASTIC SUPPLY
This means that the quantity of goods produced does not react too much to the good changing price.
Normally market forces demand that should the price of a good change, there must be a corresponding change in supply but for inelastic goods, the change is either not there or not too much.
Goods necessary for survival however are usually produced regardless of their price because people will still buy them. Not to mention, the availability of such goods is usually monitored by governments who ensure that as many people as possible can get a chance at survival by keep production levels constant.
