Answer:
A. dependent upon the circumstances involved.
Step-by-step explanation:
Scarcity means limited. A product that is plentiful means that it is available in larger quantities for some people in an area while same product could also said to be scarce for other people in other area due to limited resources.
Availability of resources is one of the determinants of scarcity. 'A' may experience scarcity if the resource available is limited or has more than one use while 'B' may experience surplus if there is more than enough for the demand.
So, in the real sense, relative scarcity can be different depending upon the circumstances involved.
